MHT CET Physics question
A simple pendulum of length and mass of bob is oscillating in a plane about a vertical line between angular limits and . For an angular displacement , the tension in the string and the velocity of the bob are and , respectively. Which of the following relations holds good under the above conditions?
Answer: (B)
Solution
Along the string the net inward force provides the centripetal force: ; (a) and (d) hold only for a bob at rest
