An electron is moving with constant velocity along $x - $ axis. If a uniform electric field is applied along $y - $ axis, then its path in the $x - y$ plane will be
Define work function of metal and write its unit.
A charge of magnitude $3e$ and mass $2m$ is moving in an electric field $\overrightarrow E .$ The acceleration imparted to the charge is
Electric field and magnetic field in Thomson mass spectrograph are applied
The fact that electric charges are integral multiples of the fundamental electronic charge was proved experimentally by
