Two particles A and B locat at (0,0) and (4,4) respectively start moving simu lataneou ly with velocities `v_(A)=-4hati` and `V_(B)=-4hatj`:

Options

A. the shortest distance between them is `4sqrt(2)m`
B. the shortest distance between them first decreases and then increases
C. the distance between them increases from the beginning
D. the magnitude of relative velocity of A w.r.t. B is 4m/s

Answer

a,c

Explanation

The shortest distane h/w them is
`AB=4sqrt(2)m`
Because the distance b/w them increases from start.
