Assertion The maximum height of projectile is always 25% of the maximum range.

Reason For maximum range, projectile should be projected at 90°.

Assertion : When $$\theta=45^{\circ}$$ or $$135^{\circ}$$, the value of $$R$$ remains the same, only the sign changes.

Reason : $$R=\frac{u^2 \sin 2 \theta}{g}$$
