Two projectiles are thrown simultaneously in the same plane from the same point. If their velocities are `v_(1)` and `v_(2)` at angles `theta_(1)` and `theta_(2)` respectively from the horizontal, then ansewer the following questions
If `v_(1)costheta_(1) = v_(2)cos theta_(2)`, then choose the incrorrect statement

A

the time of flight of both the particles will be same

B

the maximum height attained by the particles will be same

C

the trajectory of one with respect to another will be a horizontal straight line

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
`y = (V_(21(y)))/(v_(21(x)))x rArr y = (vsin theta_(2)-sin theta_(1))/(v(cos theta_(2)-cos theta_(1)))x`
`y = (sin theta_(2) -sin theta_(1))/(cos theta_(2)-cos theta_(1))x`
