A particle P is projected with velocity ...

A particle `P` is projected with velocity `u_1` at an angle of `30^@` with the horizontal. Another particle `Q` is thrown vertically upwards with velocity `u_2` from a point vertically below the highest point of path of `P`. Determine the necessary condition for the two particles to collide at the highest point.
.

A

2

B

`sqrt((3)/(2))`

C

0.5

D

1

Text Solution

Verified by Experts

The correct Answer is:
C
( c) Vertical component of both should be same.
`v_2 = v_1 sin 30^@ rArr (v_2)/(v_1) = (1)/(2) = 0.5`.
