Problem

Particle-1 is projected from ground (take it origin) at time

t = 0

, with velocity

(30\hat{i} + 30\hat{j}) \text{ ms}^{-1}

. Particle-2 is projected from

(130 \text{ m}, 75 \text{ m})

at time

t = 1 \text{ s}

with velocity

(-20\hat{i} + 20\hat{j}) \text{ ms}^{-1}

. Assuming

\hat{j}

to be vertically upward and

\hat{i}

to be in horizontal direction, match the following two columns at

t = 2 \text{ s}

Column I	Column II
(a) horizontal distance between two	(p) 30 SI units
(b) vertical distance between two	(q) 40 SI units
(c) relative horizontal component of velocity between two	(r) 50 SI units
(d) relative vertical component of velocity between two	(s) None of the above
