Write definition of unit Coulomb.
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 ?
Find change in mass of a body if it is given $+2C$ charge.
A conductor has $14.4 \times {10^{ - 19}}coulombs$ positive charge. The conductor has(Charge on electron $ = 1.6 \times {10^{ - 19}}coulombs$)
Can we neglect the quantization of charge ? If yes, then mention the situation ?
If $10^{9}$ electrons move out of a body to another body every second. how much time is required to get a total charge of $1 \,C$ on the other body?
