Question
In projectile motion assuming no air drag let t0A = t1 and tAB. The horizontal displacement from O to A is R1 and from A to B is R2. Maximum height is H and time of flight is T. Now if air drag is to be considered, then choose the correct alternative(s)
Options
A.t1 will decrease while t2 will increase
B.H will increase
C.R1 will decrease while R2 will increase
D.T may increase or decrease
Solution
As drag reduces vertical component of velocity so time to reach maximum height will decrease and it will decrease the downward vertical velocity hence time fall on earth increases.
