Question

12. Two protons are a distance of 1 x 10-10cm from each other.
The forces acting on them are
(a) nuclear force and gravitational force
(b) nuclear force and coulomb force
(c) coulomb force and gravitational force
(d) nuclear, coulomb and gravitational force​

Answer 1

The answer will be D)

Nuclear, coulomb and gravitational force

Answer 2

Answer:

(c) coulomb force and gravitational force

Explanation:

There are 4 fundamental forces in physics.

Namely Electromagnetic, Gravitational, Strong nuclear force and Weak nuclear force.

Nuclear forces are confined to an operating distance of about 10−15 metre, which is about the diameter of a proton.(In the case it doesn't act as the distance is more than the range for Stong and Weak nuclear forces).

And gravitational force is the weakest force amoung all forces and acts when there are masses(In this case they may be negligible but it exists). And electromagnetic force acts when the particles are charged, in this case they repel each other as both the particles have the same charge.
