Question
Case: You now accelerate the brick directly upwards.
What is the action-reaction pair of the force of gravity acting on the brick?
Select---the force on the brick from the hand; the force on the hand from the brick; the force on the Earth from the brick; the normal force on the brick; the weight of the brick
and which way does it point? Select---upwards; downwards; none of these

Explanation / Answer
earth attract brick by force of gravity towards the earth then brick also attarcts
earth towards itself with the same magnitude of force.
Ans the force on the Earth from the brick
Upward
-------------------------
as hand exerts force on brick upward to hold then brick also exerts force on hand
downward pushing it.
the force on the hand from the brick
downward
