Vedclass · Answer

(C) The assertion $(A)$ is true. The horizontal range $R$ of a projectile is given by the formula $R = \frac{u^2 \sin(2	heta)}{g}$. For a given initial velocity $u$,the range is maximum when $\sin(2	heta)$ is maximum,i.e.,$\sin(2	heta) = 1$,which implies $2	heta = 90^{\circ}$ or $	heta = 45^{\circ}$.The reason $(R)$ is false. The range $R$ of a projectile depends not only on the angle of projection $	heta$ but also on the initial velocity $u$ and the acceleration due to gravity $g$ $(R = \frac{u^2 \sin(2	heta)}{g})$. Therefore,it does not depend 'only' on the angle of projection.Thus,$(A)$ is true but $(R)$ is false.

Assertion $(A)$: The range of a projectile is maximum when the angle of projection is $45^{\circ}$.
Reason $(R)$: The range of a projectile depends only on the angle of projection.
