A small bob attached to a string of length l is suspended from a rigid support and rotates with uniform speed along a circle in a horizontal plane. Let θ be the angle made by the string with the vertical, then the length of a simple pendulum having the same period is

A particle suspended from a fixed point by a light inextensible thread of length L is projected horizontally from its lowest position with velocity 27gL​ ​. The thread will slack after swinging through an angle θ such that θ equal.
