Suppose the amplitude of a simple pendulum having a bob of mass $m$ is ${\theta }_0$. Find the tension in the string when the bob is at its extreme position.

Q. The bob of a simple pendulum of mass ${}^{\prime }{m}^{\prime }$ is performing oscillations such that the tension in the string is equal to twice the weight of the bob while it is crossing the mean position. The tension in the string when the bob reaches extreme position is :

Q. A simple pendulum is oscillating with an angular amplitude ${60}^{\circ }$. The ratio of tensions in the string when the bob reaches the mean position and the extreme position respectively is :

Q. The bob of a simple pendulum of mass m is oscillating with angular amplitude ${40}^{\circ }$. The tension in the string at the instant when its angular displacement is ${20}^{\circ }$ will be:

Q. A simple pendulum is oscillating with an angular amplitude ${60}^o$. If $m$ is mass of bob and $T_1$, $T_2$ are tensions in the string, when the bob is at extreme position, mean position respectively then is:

Q. A simple pendulum with a bob of mass m swings with an angular amplitude of ${40}^0$. When its angular displacement is ${20}^0$, the tension in the string greater than $mgcos{20}^0$.
