Which types of forces exist between the two protons in a helium nucleus? 1.
a repulsive electrostatic force and a repulsive gravitational force
2.
a repulsive electrostatic force and an attractive strong nuclear force
3.
an attractive electrostatic force and an attractive gravitational force
4.
an attractive electrostatic force and an attractive strong nuclear force

Option (2) is correct.

Explanation:

When two charges have equal charges they repel each other. On the other hand, if they have unequal charges they attract each other.

The force between the two protons in a helium nucleus is electrostatic charges and the force is repulsive in nature.

Also, there exists a strong nuclear force between charges.

So, a repulsive electrostatic force and an attractive strong nuclear force is the correct answer.
