If a solid and a hollow conducting sphere have same radius then
Hollow sphere will hold more maximum charge
Solid sphere will hold more maximum charge
Both the spheres will hold same maximum charge
Both the sphere can't hold charge
‘At the surface of a charged conductor electrostatic field must be normal to the surface at every point’. Explain.
Figure shows a charged conductor resting on an insulating stand. If at the point $P$ the charge density is $\sigma $, the potential is $V$ and the electric field strength is $E$, what are the values of these quantities at point $Q$
Charge density potential Electric intensity
Two identical conductors of copper and aluminium are placed in an identical electric fields. The magnitude of induced charge in the aluminium will be
An empty thick conducting shell of inner radius $a$ and outer radius $b$ is shown in figure.If it is observed that the inner face of the shell carries a uniform charge density $-\sigma$ and the surface carries a uniform charge density $ '\sigma '$
If the outer surface of the shell is earthed, then identify the correct statement(s)
Consider the shown system of two concentric thin metal shells. The inner hell has charge $Q$, while the outer shell is neutral. Potential difference between the shells is $V$. If the shell are joined by metal wire, then potential of the inner shell is
