A projectile can have the same range (R) for two angles of projection. Their initial velocities are same. If \(T_1\) and \(\mathrm{T}_2\) are times of flight in two cases, then the product of two times of flight is directly proportional to
- A \(\frac{1}{R}\)
- B \(\mathrm{R}^3\)
- C \(\mathrm{R}^2\)
- D \(R\)
Answer & Solution
Correct Answer
(D) \(R\)
Step-by-step Solution
Detailed explanation
For same range, \(R_1=R_2=R\) \(\theta_1=\theta, \theta_2=\left(90^{\circ}-\theta\right)\) \(\therefore \mathrm{T}_1=\frac{2 \mathrm{u} \sin \theta_1}{\mathrm{~g}}=\frac{2 \mathrm{usin} \theta}{\mathrm{g}}\)…
