A particle is projected from the bottom ...

A particle is projected from the bottom of an inclined plane of inclination `30^@`. At what angle `alpha `(from the horizontal) should the particle be projected to get the maximum range on the inclined plane.

Text Solution

Verified by Experts

The range is maximum at,
`alpha = pi/4 + beta/2` (given in the theory)
`=45^@ + (30^@)/2 = 60^@`.
