Two particles are projected vertically upwards with the same velocity on two different planets with acceleration due to gravities g 1 and g 2 respectively. If they fall back to their initial points of projection after lapse of time t 1 and t 2 respectively, then
Text Solution
Verified by ExpertsThe correct answer is:
B
t 1 = 
and t 2 = 
where, u is initial velocity of each ball and t 1 , t 2 are total times of flight. from here, g 1 t 1 = g 2 t 2 = 2u
