QUESTION #36 Circular Motion and Tension
A stone of mass 900 g is tied to a string and moved in a vertical circle of radius 1 m making 10 rpm. The tension in the string, when the stone is at the lowest point is (if π² = 9.8 and g = 9.8 m/s²):

QUESTION #59 Non-uniform Circular Motion
A particle is moving in a circle of radius 50 cm in such a way that at any instant the normal and tangential components of its acceleration are equal. If its speed at t = 0 is 4 m/s, the time taken to complete the first revolution will be (1)/(α)[ 1 - e-2π ] s, where α = ________.
