Question

Select One Option Correct from the following :A simple pendulum of length L and bob mass M is oscillating in a plane about a vertical line between angular limits $-\phi \ and +\phi$. For an angular displacement $\theta (|\theta|\ \textless \ \phi)$ the tension in the string and the velocity of the bob are T and $\upsilon$ respectively. The following relations hold good under the above conditions,
(A)$T \cos \theta= Mg$
(B)$T -Mg \cos\theta = M \upsilon^2/L$
(C)The magnitude of the tangential acceleration of the bob $|a_T|= g \sin \theta$
(D)$T = Mg \cos \theta$
