Force acting on a particle moving in a straight line varies with the velocity of the particle as $F = \frac{K}{v}$ . Here K is a constant . The work done by this force in time t is :

Options:

Answer:

Solution:

Work done by the force on particle is

$w = \int dw = \int Fdx w = \int \frac{K}{v} dx w = \int \frac{K}{dx} dt dx w = \int K dt$
