Question

25. The magnitude of change in velocity of a particle
having speed v is v during a time interval At while
moving in a uniform circular motion. The magnitude
of average force on the particle is proportional to​

Answer 1

Answer:As in the given question the value of change in velocity of a particle having v speed with respect to time t is given as dv/dt which can be considered as the acceleration of the particle.

As the given particle is moving in a circular motion then the average force of the particle will be inwards and be equal to mv^2/r and hence the average force will be directly proportional to the velocity of the particle.
