MHT CET 2026 Physics question

A simple pendulum oscillates with an angular amplitude . If the maximum tension in the string is twice the minimum tension then is

(A)cos (0.75)Correct
(B)cos (0.5)
(C)sin (0.5)
(D)sin (0.75)

Answer: (A)

Solution

At the extreme position the speed is zero, so the tension is minimum: . At the mean position the speed satisfies , so the tension is maximum: . Given :
