@LaveshGupta @Sanjay_S @AshWin pls help

c option is 1/root (3)

What’s the given answer?

d option @Cooljet123

Yes, I think it is correct, because if we write impulse equation, we get v_f as \sqrt{3}. But coefficient of restitution will be greater than 1 if that is the case. So, the given case is not possible.
