A particle moves under the effect of a forceF Cx from x0 toxx. The work donein the process isd)CxZero2

Answer»

Work done = Force x displacementAs force is changing with the displacement we have to take a small element dx and then integrate it from x=0 to x= x1.

Work = intergration( Cx * dx) from x =0 to x= x1

(1/2) * Cx^2 and putting values of definite integration we get.Work = C x1^2 /2.Option b
