Answer 2

While measuring an electric field we use 1. 6×10−19 coulombs as a small charge.

Explanation:

• Charge is known to be quantized. It is connoted in multiple integers of small units that is referred to as an elementary charge.
• This is a positive value for a proton and a negative value associated with an electron. The charged body is going to have a positive charge if the electrons found in them are less as this could be vice versa.
