Write an equation for potential due to linear charge distribution.
In the following figure two parallel metallic plates are maintained at different potential. If an electron is released midway between the plates, it will move
If the potential of the inner shell is $10\,V$ and that of the outer shell is $5\,V$, then potential at the centre will be....$V$
A uniform electric field of $400 \,v/m$ is directed $45^o$ above the $x$ - axis. The potential difference $V_A - V_B$ is -.....$V$
An electric charge $10^{-3}\ \mu C$ is placed at the origin $(0, 0)$ of $X-Y$ coordinate system. Two points $A$ and $B$ are situated at $(\sqrt 2 ,\sqrt 2 )$ and $(2, 0)$ respectively. The potential difference between the points $A$ and $B$ will be......$V$
A table tennis ball which has been covered with conducting paint is suspended by a silk thread so that it hang between two plates, out of which one is earthed and other is connected to a high voltage generator. This ball
