Questions
Two particles are projected with same initial velocity one makes an angle with horizontal while other makes an angle with vertical. If their common range is R, then product of their time of flight is directly proportional to :
detailed solution
Correct option is A
t1=2usinθg and t2=2ucosθg⇒t1t2=4u2sinθcosθg2=2Rg∝RTalk to our academic expert!
Similar Questions
Assertion : When the velocity of projection of a body is made n times, its time of flight becomes n times.
Reason : Range of projectile does not depend on the initial velocity of a body.
