Question

Two objects A and B have masses of m and 4m respectively and insignificant space between them. At t=0 the objects are left to freely fall from the same height h. Consider air friction insignificant.
If object A reaches the ground at t=2s, B is going to reach the ground at
a) t=1s b) t=4s c) t=2s
