Question

a body is displaced from x=x1 to x=x2 by a force of 2x. The work done is​

Answer 1

Work done is force *displacement

So it is 2x(x2-x1).

Just this much

I Think this question comes from 9 standard student haaa..

Answer 2

Answer:(x2)²- (x1)²

Explanation:

Work done= \int\limits_{x1}^(x2) F dx

                 =\int\limits_{x1}^(x2) 2x dx

                 = 2 [x²/2]|_(x1)^(x2)

                 = (x2)²- (x1)²
