Q: A hollow sphere of mass m starting from rest rolls down, without slipping, on an inclined plane of inclination θ. What is the total energy of the sphere after 10-5 s if velocity after 10-5 s is v ?

(a)$\displaystyle \frac{5}{6}mv^2$

(b)$\displaystyle \frac{2}{3}mv^2$

(c)$\displaystyle 10^{-5}mv^2$

(d)$\displaystyle \frac{mv^2}{10^{-5}}$

Ans: (a)
