A simple pendulum of length L and mass (bob) M is oscillating in a plane about a vertical line between angular limit `-phi` and `+phi`. For an angular displacement `theta(|theta|ltphi)`, the tension in the string and the velocity of the bob are T and V respectively. The following relations hold good under the above conditions:

Options

A. `Tcos theta=Mg`
B. `T-Mg cos theta=MV^(2)//L`
C. The magnitude of the tangential acceleration of the bob `|a_(T)|=g sin theta`
D. `T=Mg cos theta`

Answer

B, C
