1. A body, tied to a string of length L, is revolved in a verticle circle with minimum velocity when the body reaches the uppermost point, the strings breaks and the body moves under earths gravitational field along a parabolic path. The horizontal range (x = AC) of the body will be
--image--
a) L
b) 2L
c) $2\sqrt{2}L$
d) None of these

2. Two particles start together from a point O and slide down straight on smooth wires inclined at 30⁰ and 60⁰ to the vertical and in the same vertical plane and on the same side of vertical through O. The relative acceleration of the second with respect to first will be in magnitude and direction as
a) $\frac{g}{2}$ in the vertical direction
b) $\frac{g\sqrt{3}}{2}$ inclined at 45⁰ to vertical
c) $\frac{g}{\sqrt{3}}$ inclined at 60⁰ to vertical
d) g in the vertical direction
