The vehicles carrying inflammable fluids usually have metallic chains touching the ground:
To conduct excess charge due to air friction to ground and prevent sparking.
To alert other vehicles.
To protect tyres from catching dirt from ground.
It is a custom.
$A$ and $B$ are concentric conducting spherical shells. $A$ is given a positive charge while $B$ is earthed. Then :-
A hollow conducting sphere is placed in an electric field produced by a point charge placed at $P$ as shown in figure. Let ${V_A},{V_B},{V_C}$ be the potentials at points $A,B$ and $C$ respectively. Then
For the situation shown in the figure below, mark out the correct statement
A non uniformly shaped conductor is charged then at it's sharpest point
If electric potential of the inner sphere is $10\, volt$ and that of the outer shell is $50\, volt$ then potential at common centre is :-......$V$
