Shown in the figure is a shell made of a conductor. It has inner radius a and outer radius b, and carries charge. Q at its centre is a dipole `vecp` shown in this case:
A
surface charge density on the inner surface is uniform and equal to `((Q//2))/(4pia^(2))`
B
electric field outside the shell is the same as that of a point charge at the centre of the shell
C
surface charge density on the outer surface depneds on `|vecp|`
D
surface charge density on the inner surface of the shell is zero everywhere
Shown in the figure a spherical shell with an inner radius 'a' and an outer radius 'b' is made of conducting metarial. A charge +Q is placed at the centre of the spherical shell and a total charge -q s placed on the shell. Charge -q is districuted on the surfaces as :
A coaxial cable carries the a current i in the inside conductor of radius a as shown in figure-4.80 and the outer conductor of inner radius b and outer radius c carries a current i' in opposite direction. Find the magnetic induction due to the coaxial cable at distance r from the central axis of the cable for (a) r gt a , (b) a lt r lt b and (c) b gt r gt c
A point charge +q is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.
A conducting spherical shell having inner radius a and outer radius b carries a net charge Q. If a point charge q is placed at the centre of this shell, then the surface charge density on the outer surface of the shell is given as:
Both question (33) and (34) refer to the system of charges as shown in the figure. A spherical shell with an inner radius 'a' and an outer radius 'b' is made of conducting material. A point charge +Q is placed at the centre of the spherical shell and a total charge -q is placed on the shell. Assume that the electrostatic potential is zero at an infinite distance from the spherical shell. The electrostatic potential at a distance R(a lt R lt b) from the centre of the shell is
A conducting sphere of radius R and a concentric thick spherical shell of inner radius 2R and outer radius 3R is shown in figure. A charge +10Q is given to the shell and inner sphere is earthed. Then charge on inner sphere is
A point charge q is placed inside a conducting spherical shell of inner radius 2R and outer radius 3R at a distance of R fro the centre of the shell. The electric potential at the centre of shell will (potential at infinity is zero).
