Question
In the given figure for a projectile
✓
Answer
(b)
The equation of trajectory for point ' $P$ 'can be written as :
$y=x \tan \theta\left(1-\frac{x}{R}\right)=x_1 \tan \theta\left(1-\frac{x_1}{x_1+x_2}\right)=x_1 \tan \theta\left(\frac{x_1+x_2-x_1}{x_1+x_2}\right)$
$y=\frac{x_1 x_2}{x_1+x_2} \tan \theta$
