Question : What is the relative charge of a proton and neutron?
Option 1: -1 and +1 respectively
Option 2: +1 and -1 respectively
Option 3: +1 and 0 respectively
Option 4: -1 and 0 respectively
Correct Answer: +1 and 0 respectively
Solution : The correct answer is +1 and 0 respectively .
While having almost equal masses, protons and neutrons have different electric charges. A neutron is neutral and has no net electric charge, whereas a proton has a positive charge. A proton possesses an elementary charge of about +1. Since a neutron lacks a net electric charge, its charge is almost always near zero.
