Length of a simple pendulum is 2 m and mass of its bob is 2 kg. If the tension in the string exceeds 100 N, it will break. If and the bob is whirled in a horizontal plane, the maximum angle through which the string can make vertical during rotation is

Answer: (C)

Solution

Vertical balance: T cos(θ) = mg, so cos(θ) = 20/100 = 2/10 at the breaking tension. /5) would need T = 50
