All are examples of electric forces except a. a neutron pushing on another neutron b. an electron pushing on a proton c. an electron pushing on another electron

A) a neutron pushing on another neutron.

Explanation:

Neutrons have no charge, therefore, there is no electric force among them. Protons and electrons on the other hand do have electric charge (electrons negative charge and protons positive charge) that generate electric forces between them that can be repelling forces (if the charges are of the same sign), or attractive forces (if the charges are of opposite signs).

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
