The specific charge of an electron is
$1.6 \times {10^{ - 19}}coulomb$
$4.8 \times {10^{ - 10}}stat\;coulomb$
$1.76 \times {10^{11}}coulomb/kg$
$|8| \times {10^{ - 15}}Hz$
Which particles are responsible for conductivity of metals ?
Positive rays was discovered by
A charge of magnitude $3e$ and mass $2m$ is moving in an electric field $\overrightarrow E .$ The acceleration imparted to the charge is
In Thomson experiment of finding $e/m$ for electrons, beam of electron is replaced by that of muons (particle with same charge as of electrons but mass $208$ times that of electrons). No deflection condition in this case satisfied if
The cathode rays have particle nature because of the fact that
