Question

a body is under the action of the equal and opposite forces each of 5 n. the body is displaced by 2m. the work done is ___________.​

Answer 1

Work done will be 0 because, we know , force is opposite , so it will equalise them, and so the net force will be zero,

w= 0× 2

=0

Answer 2

Explanation:

Work done =Force ×Displacement

=5n×2m

=10 joules

But the body is under the action of the equal and opposite forces So,it must be 0
