What Is The Number Of Minimum Forces That Can Give Zero Resultant?

Can three unequal vectors add up to zero?

Since a scalene triangle exists, three unequal vectors can add up to zero.

The conditions for three vectors to form a triangle are: …

magnitude of sum of two vectors must be equal to the magnitude of third.

All three should have different directions..

Which of the following set of forces Cannot give zero resultant?

let us considered three forces in equilibrium and represents three sides of a triangle a,b and c. We know that, In the triangle, addition of the two sides is greater than the third side then the resultant might be zero but when addition of the two sides is less than the third side then the resultant can not zero.

What is the angle between two vectors forces of equal magnitude?

Answer. The answer is theta=cos inverse -17/18.

Can 2 vectors of unequal magnitudes add up to zero?

Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero. Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.

What is the minimum number of vectors with unequal magnitudes?

threeAssertion: The minimum number of vectors of unequal magnitude required to produce zero resultant is three. Reason: Three vectors of unequal magnitude which can be represented by the three sides of a triangle taken in order, produce zero resultant.

Can two nonzero perpendicular vectors be added together so their sum is zero?

Can 2 non-zero perpendicular vectors be added together so that their sum is zero? ANSWER: No. The sum of two perpendicular non-zero vectors can never be zero.

What is the formula for resultant vector?

Suppose two ships are moving in different directions at some angle between them and we have to find the distance between them we use the formulaR2=a2+b2−2abcosθ But if we have to find the resultant between two forces we use the formulaR2=a2+b2+2abcosθ.

What is the least number of unequal non zero vectors that can be added to give a resultant equal to zero?

threeWell the answer is three. Clearly two vectors that are unequal can’t sum to zero and by polygon law of addition of vectors, you know 3 or more vectors can be summed to zero. So minimum is 3. Originally Answered: What is the minimum number of vectors in different magnitude can be added to give a zero resultant?

When two vectors are added together their resultant is minimum when the angle between them is?

The resultant of two vector is minimum when both vectors are equal and in opposite direction i.e. the angle between the vector is 180 degrees.

Is distance can be zero?

Answer Expert Verified Distance can be zero , when the object is at rest or in other words , is at a stationary position. But , distance is not always zero even if displacement is zero. … distance = circumference of the circle. displacement = shortest distance possible between initial and final position.

What is the minimum number of vectors in different planes?

Four vectors in different planes may give zero resultant.

Can the resultant of two velocities have zero magnitude?

Answer. Yes, two velocities can be added to give a resultant of 0 magnitude. The velocities should be equal in magnitude and opposite in direction.

Does it make sense to call a physical quantity a vector when its magnitude is zero?

Does it make sense to call a physical quantity a vector when its magnitude is zero ? Yes,null vector has a definite physical significance.

What are the maximum and minimum resultant of two forces?

The resultant of two forces acting on the same point is maximum when the forces are acting in the same direction and minimum when they operate in opposite direction. When the two forces are acting in the same direction the angle between the direction to the two forces is 0.

What is the minimum number of vectors that can give zero?

three vectorsAccording to the Triangle Law of vector addition, a minimum of three vectors are needed to get zero resultant. So we can say that a minimum of 3 coplanar vectors is required to represent the same physical quantity having different magnitudes that can be added to give zero resultant.

What are minimum number of unequal forces whose vector sum is zero?

threeWe know that only triangle is closed figure of minimum side, Sides of triangle represent vector, So the minimum number of unequal vectors whose vector sum can be zero is three.

Which of the following pairs of forces Cannot be added to give a resultant force of 4 N?

So 3N and 8N cannot give resultant as 4N.

Can a vector have a component equal to zero and still have a non zero magnitude explain?

Yes, a vector can have a component equal to zero and still have a nonzero magnitude.

What is maximum number of components into which a vector can be split?

A vector can be split into infinite components (but only 3 orthogonal ones)

What is the cross product of equal vectors?

Since two identical vectors produce a degenerate parallelogram with no area, the cross product of any vector with itself is zero… Applying this corollary to the unit vectors means that the cross product of any unit vector with itself is zero.

How do you calculate resultant force?

To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.
