A car is moving along a circular track of radius 10sqrt(3) m with a constant speed of 36kmph. A plumb bob is suspended from the roof of the car by a light rigid rod of length Im. The angle made by the rod with the track is ( g= 10ms^(-2) )

A bob of mass 100 g tied at the end of a string of length 50 cm is revolved in a vertical circle with a constant speed of 1 ms^(-1) . When the tension in the string is 0.7 N, the angle made by the string with the vertical is (g = 10 ms^(-2))

The force excreted by string on the pulley is (g=10ms^(-2))
