A ball is projected from a point on an inclined plane horizontally. It takes `1/(sqrt(2))` seconds to strike the plane. If the incline plane makes an angle of `30^(@)` with horizontal then find the range of the ball on incline plane in meters`[g=10m//s^(2)]`

Text Solution

Verified by Experts

The correct Answer is:

`AC=1/2xx10xx(1/(sqrt(2)))^(2)=2.5mimpliesAB=5m`
