Question
Two particles P and Q are moving with velocities of (î + ĵ) and (- î + 2ĵ) respectively. At time t = 0, P is at origin, and Q is at a point with position vector (2î + ĵ). Then the shortest distance between P & Q is : -
Options
A.
B.
C.√5
D.
Solution
So from the sine rule
⇒ xm.= √5 × 2sin
cos 
= √5 × 2 ×
