A simple pendulum of length L and mass (bob) M is oscillating in a plane about a vertical line between angular limits \[-\varphi \] and\[+\varphi \]. For an angular displacement\[\theta (|\theta |

• A.            \[T\cos \theta =Mg\]
• B.  \[T-Mg\cos \theta =\frac{M{{v}^{2}}}{L}\]
• C.            The magnitude of the tangential acceleration of the bob \[|{{a}_{T}}|\,=g\sin \theta \]
• D.            \[T=Mg\cos \theta \]
