A projectile can have the same range 𝑅 for two angles of projection. If 𝑇1 and 𝑇2 be the times of flights in the two cases, then the product of the two times of flights is directly proportional to

Question : A projectile can have the same range 𝑅 for two angles of projection. If 𝑇1 and 𝑇2 be the times of flights in the two cases, then the product of the two times of flights is directly proportional to

(A) \dfrac{1}{R^{2}}

(B) \dfrac{1}{R}

(C) R

(D) R^{2}

Answer : option (C)

Solution :

A projectile can have the same range 𝑅 for two angles of projection. If 𝑇1 and 𝑇2 be the times of flights in the two cases, then the product of the two times of flights is directly proportional to
