Question 107 of 172

A stone projected with a velocity u at an angle θ with the horizontal reaches maximum height H1. When it is projected with velocity u at an angle π2θwith the horizontal, it reaches maximum height H2. The relation between the horizontal range R of the projectile, H1 and H2 is 

(1) R=4H1H2

(2) R = 4(H1H2)

(3) R = 4(H1 + H2)

(4) R=H12H22
