Question

A force can exist between two charged particles or objects even if they're as small as subatomic particles. Between which of these would an attractive force exist?
A. proton-proton
B. neutron-proton
C. proton-electron
D. electron-electron

Answer 1

If both particles have the SAME electrical charge, then they repel.
If they have DIFFERENT electrical charge, then they attract.

Protons have  +  charge .
Electrons have  -  charge .

So two protons (A) or two electrons (D) push apart.

One proton and one electron (C) pull together.

Answer 2

Answer :

The attractive force exist between proton - electron.

(C) is correct option.

Explanation:

If both particles have like charges then the particles repel each other .

If both particles have unlike charges then the particles attract to each other.

Proton and electron have positive and negative charge respectively.

Neutron has no charge.

So, The attractive force exist between two charged particles proton and electron.

Hence, The attractive force exist between proton - electron.
