In vertical circular motion of a bob,match the entries of List-$I$ with entries of List-$II$. Here,$v_0$ is the velocity of the bob at the lowest point.
List-$I$ (Speed at lowest point) List-$II$ (Possible situation) $(P) v_0 = \sqrt{5 g \ell}$ $(1)$ Tension at lowest point $= 6 mg$ $(Q) v_0 = \sqrt{g \ell}$ $(2)$ String will slack for a finite time $(R) v_0 = 2 \sqrt{g \ell}$ $(3)$ Bob will oscillate $(S) v_0 = 3 \sqrt{g \ell}$ $(4)$ Tension at highest point $= 4 mg$
