Figure shows as rod of length 20 cm pivoted near an end and which is made to rotate in a horizontal plane with a constant angular speed. A ball ofmass m is spuspended by a string angular also of length 20 cm from the other end of the rod. If the angle `theta` made by the stirng with the vertical is `30^0`. find the anglular speed of the rotation. Take `g=10 m/s^2`
