Problem

Particle-1 is just dropped from a tower. 1 s later particle-2 is thrown from the same tower horizontally with velocity

10 \text{ ms}^{-1}

. Taking

g = 10 \text{ ms}^{-2}

, match the following two columns at

t = 2

Column I	Column II
(a) Horizontal displacement between two	(p) 10 SI units
(b) Vertical displacement between two	(q) 20 SI units
(c) Magnitude of relative horizontal component of velocity	(r) $10\sqrt{2}$ SI units
(d) Magnitude of relative vertical component of velocity	(s) None of the above
