Question

Mark the incorrect statement:
Two objects of different masses falling towards the earth from the same height have
(a) equal velocities at equal heights
(b) equal acceleration at equal heights
(c) equal momenta at equal heights
(d) equal force of gravity at equal heights

Answer 1

Answer:

The equal force of gravity at equal heights

Explanation:

Answer 2

Answer:

Both C and D can be the correct answer.

Explanation:

They don't have equal momenta because:

p = mv

Although, velocity is same, masses are different. So, their momenta are unequal.

The don't have equal force of gravity because:

F = mg

Although, g is constant, masses are different. So, gravitational attractions are unequal.
