    A particle of mass m is moving in a circular path of constant radius r such that centripetal acceleration a c varying with time is \[{{10}^{-6}}{{m}^{2}}\], where k is a constant. What is the power delivered to the particle by the force acting on it?

    A)                  \[{{10}^{29}}\]                 

    B)  \[250\times {{10}^{-3}}m/s\]

    C)  \[25\times {{10}^{-3}}m/s\]                      

    D)  \[2.50\times {{10}^{-3}}m/s\]

    Correct Answer: C

    Solution :

                     \[\frac{hv}{4}\] \[\frac{hv}{3}\] \[\frac{hv}{2}\] \[\frac{2hv}{3}\] According to work-energy theorem, change in kinetic energy is equal to work done                 \[30\mu A\] Thus, power delivered to the particle \[90\mu A\]
