Question

The magnitude of non-contact force depends upon:

• A. distance between the two bodies
• B. mass of the two bodies
• C. chemical properties of the two bodies
• D. all of the above

Answer 1

Answer: (A)

distance between the two bodies

Magnitude of non-contact force decreases with increase of separation between the two bodies.

As we know, $F=K\frac{q_1{q}_2}{r^2}$

From the above equation we can say that the magnitude of non-contact force depends on separation.
