A simple pendulum consists of a bob of mass m and a light string of length l as shown in the fig. another identical ball moving with the small velocity `v_0` collides with the pendulum's bob and sticks to it. For this new pendulum of mass 2 m, mark out the correct statements (s).

A

Time period of the pendulum is `2pi sqrt(l/g)`

B

The equation of motion for this pendulum is `theta = (v_0)/(2sqrt(gl) sin [sqrt(g/l)t]`

C

The equation of motion for this pendulum is `theta = (v_0)/(2sqrt(gl)) cos [sqrt(g/l) t]`

D

Time period of the pendulum is `2pi sqrt((2l)/(g))`
