Find the angle of projection for a projectile motion whose rang `R` is (n) times the maximum height `H`.

Explanation

To find the angle of projection for a projectile motion whose range \( R \) is \( n \) times the maximum height \( H \), we can follow these steps:

### Step 1: Write the equations for range and maximum height
The range \( R \) of a projectile is given by the formula:
\[ R = \frac{u^2 \sin 2\theta}{g} \]
where \( u \) is the initial velocity, \( \theta \) is the angle of projection, and \( g \) is the acceleration due to gravity.
