Question
The diagram show a uniformly charged hemisphere of radius R. It has volume charge density . If the3 electric field at a point 2R distance above its centre is E then what is the electric field at the point which is 2R below its centre ?
Options
A.
+ E
+ EB.
+ E
+ EC.
+ E
+ ED.
+ E
+ ESolution
Apply principle of superposition
