Explanation
Effective air separation between them becomes infinite so force becomes zero.
On rubbing glass rod with silk, excess electron transferred from glass to silk. So, glass rod becomes positive and silk becomes negative.
Potential energy depends upon the charge at peaks of irregularities. Since, every event in the universe leads to the minimisation of energy.
Since, both are metals so equal amount of charge will induce on them.
In case of spherical metal conductor the charge quickly spreads uniformly over the entire surface because of which charges stay for longer time on the spherical surface. While in case of non-spherical surface, the charge concentration is different at different points due to which the charges do not stay on the surface for longer time.
Nuclear force binds the protons and neutrons in the nucleus of an atom.
Because current flows from higher potential to lower potential.
All charge resides on the outer surface so that according to Gauss’s law, electric field inside a shell is zero.
In non-uniform electric field. Intensity is more, where the lines are more denser.
ABCDE is an equipotential surface, on equipotential surface no work is done in shifting a charge from one place to another.
Electric lines of force never intersect the conductor. They are perpendicular and slightly curved near the surface of conductor.
