Question

Which is the biggest physical quantity?

• A. A coulomb
• B. Charge on an electron
• C. Charge on a proton
• D. Charge on a neutron

Answer 1

The correct option is A A coulomb

Charge on an electron =$-e$

and charge on a proton =$e$ where $e=1.6\times {10}^{-19}C$

Charge on a neutron is 0.

Hence, of all given charge $1C$ is biggest.

Answer-(A)
