In the figure shown, the two projectiles are fired simultaneously. The minimum distance between them during their flight is

A

20 m

B

`10 (sqrt3) m`

C

10 m

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
`a_1 = a_2 = g`



`:. a_(12) = 0`
`:.` Relative motion between them is uniform.
Relative velocity `v_(21)`
`d_(min) = 20(sqrt3) sin 30^@`
`= 10(sqrt3)m` .
