Question

A coffee mug of weight W is at rest on a table. What set of forces, if any, are acting on the mug?


A. a downward force of magnitude W

B. both a downward force and an upward force, each of magnitude W

C. an upward force of magnitude W

D. no forces

Answer 1

Your Answer:

B) Both, a downward force (gravitational force) and an upward force (normal reaction force), each of magnitude W.

Hope this helps you..

Answer 2

Hi friend!

Answer:

(B) Both a downward force and an upward force of magnitude W.

Reason:
There is gravitation which is pulling the mug, it will be of the same magnitude (W).
And according to Newton's third law of motion, for every action there is an equivalent and opposite reaction. So when the mug is applying force on the table (due to gravity), the table is returning the force with the same magnitude (W).

And the object remains stationary as the net force is 0.
Therefore, the answer is (B).
