speed V is R

Best Answer

The position from where block is released will correspond to upper extreme position of oscillation. For equilibrium if block descends by x, then according to force balance equation

force balance equation

The block will further go downward by x to reach the lower extreme. So, the maximum displacement will be 2x.
