Question

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

(a) $\frac{K}{v^{2}} t$

(b) $\frac{2 K t}{v^{2}}$

(c) $K t$

(d) $2 K t$

Answer 1

The work done by this force in time $t$ is $K t$. So, The correct option of this question will be (C).
