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 bob at lowest point \& \( \mathrm{T} \) is tenision in string.
\( \mathrm{P} \)
W
List-I \( \quad \) List-II
(speed at lowest point) (possible situation)
(P) \( \quad v_{0}=\sqrt{5 g \ell} \)
(1) \( \mathrm{T}_{\text {lowest }}=6 \mathrm{mg} \)
(Q) \( \quad \mathrm{v}_{0}=\sqrt{\mathrm{g} \ell} \)
(2) string will slack for a
finite time
(R) \( \mathrm{v}_{0}=2 \sqrt{\mathrm{g} \ell} \)
(3) bob will oscillate
(S) \( \quad v_{0}=3 \sqrt{\mathrm{g} \ell} \)
(4) \( \mathrm{T}_{\text {highest }}=4 \mathrm{mg} \)
