Question

Two balls of masses in ratio $1:2$ are dropped from the same height. Find the ratio between their velocities when they strike the ground:

• A. $1:2$
• B. $2:1$
• C. $1:1$
• D. $1:4$

Answer 1

The correct option is C $1:1$

We know from kinematics equations of motion $v=\sqrt{2gh}$.From this it is very clear that velocity of any body depends on only height it is falling but not the mass.Hence two bodies will have in the ratio of 1 is to 1.
