Question

if a number of force act on a body and the body is in static or dynamic equilibrium then work done is​

Answer 1

Answer:

Work done =0

Explanation:

It is given that after applying a number of forces the body is static .

So, Resultant force = mass * acceleration

F = m * a

F = m * 0

F = 0.

And ,

Work done = F*S cos theta

W = 0 * S cos theta

W = 0
