A particle of mass 10 g moves along a circle of radius `6.4` cm with a constant tangential acceleration. What is the magnitude of this acceleration. What is the magnitude of this acceleration, if the kinetic energy of the particle becomes equal to `8xx10^(-4)`J by the end of the second revolution after the beginning of the motion?

Options

A. `0.18m//s^2`
B. `0.2m//s^2`
C. `0.1m//s^2`
D. `0.15m//s^2`

Answer

C
