The minimum charge on an object is
$1$ coulomb
$1$ stat coulomb
$1.6 \times {10^{ - 19}}$ coulomb
$3.2 \times {10^{ - 19}}$ coulomb
By which instrument, the charge on object can be detected ?
What is the meaning of addition of charges ?
A body can be negatively charged by
How can you represent experimentally that $(i)$ there are two types of charges and $(ii)$ there is repulsion between two like charges and attraction between two unlike charges ?
Sure check for presence of electric charge is
