Two guns A and B can fire bullets at speeds 1 km/s and 2 km/s respectively. From a point on a horizontal ground, they are fired in all possible directions. The ratio of maximum areas covered by the bullets fired by the two guns, on the ground is :

TestHub · Accepted Answer

Maximum range R = g u 2 ​ , and the covered area A = π R 2 . A ∝ R 2 ∝ u 4 A 2 ​ A 1 ​ ​ = ( u 2 ​ u 1 ​ ​ ) 4 = ( 2 1 ​ ) 4 = 16 1 ​ Correct option: (D)
