Question

a body is under the action of two equal and opposite forces each of 3 Newton of the body is displaced by 2 metre the work done is

Answer 1

If the body is having 2 equal and opposite forces it can't displaced.

Answer 2

Given:

A body is acted upon by two equal and opposite forces of 3 N.

To Find:

Work done on it for moving it by 2m.

Solution:

The work done on an object is defined as the dot product of the force vector and the displacement vector, i.e. force times the displacement along the direction of the force.

In this case, the net force on the body is 0 since equal and opposite forces cancel each other.

So the work done W=F.s=Fscosθ=0.

Hence, the work done on the body = 0.
