(C) The power $P$ delivered by a force $F$ acting on a particle moving with velocity $v$ is given by the formula $P = F \cdot v$.Substituting the given expression for force $F = \frac{K}{v}$ into the power formula,we get $P = \left( \frac{K}{v} \right) \cdot v = K$.Since $K$ is a constant,the power delivered by the force is constant over time.The work done $W$ by a constant power $P$ over a time interval $t$ is given by $W = P \cdot t$.Substituting $P = K$,we obtain $W = K \cdot t$.

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