A rod of length 'L' is hung from its one end and a mass 'm' is attached to its free end. What tangential velocity must be imparted to 'm', so that it reaches the top of the vertical circle? (g = acceleration due to gravity)

Options:

Answer:

Solution:

$2 gL$ $h = 2 L$ $\frac{1}{2} mv^{2} = mg 2 L$ $v_{2} = 4 gL$ $v = 2 gL$
