A small sphere of mass 200 gm is attached to an inextensible string of length 130 cm whose upper end is fixed to the ceiling. The sphere is made to describe a horizontal circle of radius 50 cm. Calculate the time period of this conical pendulum and the tension in the string. ( 
2 = 10)

CHECK THE SOLUTION.
sec., 
N (with π 2 = 10) ( π 2 = 10)
Sol. m = 200 g = 0.2 kg, g = π 2 m/s 2
Time period = 2 π 
= 2 π 
= 2
