Figure shown 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` ?

A

`{:("Charge density","Potential","Electric intensity"),(gt sigma,gtV,gtE):}`

B

`{:("Charge density","Potential","Electric intensity"),(gt sigma,V,gtE):}`

C

`{:("Charge density","Potential","Electric intensity"),(lt sigma,V,E):}`

D

`{:("Charge density","Potential","Electric intensity"),(lt sigma,V,ltE):}`

Text Solution

Verified by Experts

The correct Answer is:
D
V is same due to equipotential surface
`:. E prop 1/r^2 , :. E_Q lt E_P`
similarly `sigmaprop 1/r^2 , :. [sigma_Qlt sigma_P]`
