Question

A projectile is projected from the base of an inclined plane of inclination '$\alpha$'. The angle of projection of the projectile with the ground is $\theta$. If it strikes the incline plane at it's maximum height from the ground, then, (assume the plane of motion contains the line of greatest slope on the incline plane)

• A.
• B.
• C.
• D. We can not define a relationship between and as it will depend one the speed of projection

Answer 1

The correct option is B

From triangle,

$\frac{b}{x}$ = tan $\alpha$

tan$\alpha$ = $\frac{h_{max}}{\frac{R}{2}}$=$\frac{tan\left(\theta \right)}{2}$
