A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point \(P\) making an angle \(\theta\) from the horizontal, the ratio of the speed \(v\) of the bob at point \(P\) to its initial speed \(v_0\) is:
A mass m is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when :
A body initially at rest and sliding along a frictionless track from a height h (as shown in the figure) just completes a vertical circle of diameter AB = D. The height h is equal to
What is the minimum velocity with which a body of mass \(m\) must enter a vertical loop of radius R so that it can complete the loop ?
