Q.

A simple pendulum, made of a string of length l and a bob of mass m, is released from a small angle $θ_{0}$ . It strikes a block of mass M, kept on a horizontal surface at its lowest point of oscillations, elastically. It bounces back and goes up to an angle $θ_{1}$ . Then M is given by

A
$m (\frac{θ _{0} + θ _{1}}{θ _{0} - θ _{1}})$
B
$\frac{m}{2} (\frac{θ _{0} - θ _{1}}{θ _{0} + θ _{1}})$
C
$\frac{m}{2} (\frac{θ _{0} + θ _{1}}{θ _{0} - θ _{1}})$
D
$m (\frac{θ _{0} - θ _{1}}{θ _{0} + θ _{1}})$
