The number of electrons in $1.6\, C$ charge will be
${10^{19}}$
${10^{20}}$
$1.1 \times {10^{19}}$
$1.1 \times {10^{2}}$
Which scientist represented the types of charges ?
Why only electron can transfer from one body to another body in frictional electrics ?
A small sphere of radius $r_{1}$ and charge $q_{1}$ is enclosed by a spherical shell of radius $r_{2}$ and charge $q_{2} .$ Show that if $q_{1}$ is positive, charge will necessarily flow from the sphere to the shell (when the two are connected by a wire) no matter what the charge $q_{2}$ on the shell is.
Give examples of non-conductors and conductors.
When the charge is considered as point ?
