Question 193: Electrostats & Capacitance

Question

Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,

Accepted Answer

Net charge on sphere = $$-20+20$$ = 0
When we brought +q charge near neutral conducting sphere induction no produced.
So, net charge on sphere should be zero.
When +q is placed option (d).
Outside the conducting sphere, rearrange of charge taken place on sphere.

Answer

negative and distributed uniformly over the surface of the sphere

Answer

negative and appears only at the point on the sphere closest to the point charge

Answer

negative and distributed non-uniformly over the entire surface of the sphere

Answer

zero
