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 ared fired in all possible directions. The ratio of maximum areas covered by the bullets fired by the two guns, on the ground is :

A

`1 : 2 `

B

` 1 : 16`

C

` 1 : 8`

D

` 1 : 4`

Text Solution

Verified by Experts

The correct Answer is:
B
` (A_(1))/(A_(2)) = (pi (R^(2)max)_(1) )/(pi (R^(2)max)_(2)) = (u_(1)^(4))/(u_(2)^(4)) = (1)/(16) ` [`:. `Max . range ` = (u^(2))/( g)` ]
