A simple pendulum of length L and mass (...

A simple pendulum of length L and mass (bob) M is oscillating in a plane about a vertical line between angular limits `-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
`T-Mgcostheta=(Mv^(2))/(L)`
`T costheta=Mg`
The magnitude of the tangential acceleration of the bob `|a_(T)|=gsintheta`
`T=Mgcostheta`

A
