A particle suspended from a fixed point, by a light inextensible thread of length L is projected horizontally from its lowest position with velocity (7gL/2)^(1/2) . The thread will slack after swinging through an angle theta , such that theta equal

A heavy particle hanging from a fixed point by a light inextensible string of length l is projected horizontally with speed (gl) . Then the speed of the particle and the inclination of the string to the vertical at the instant of the motion when the tension in the string equal the weight of the particle-
