Consider an Uncharged Conducting Sphere. A Positive Point Charge is Placed Outside the Sphere. The Net Charge On the Sphere | Bzziii

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

(i) negative and uniformly distributed over the surface of sphere 

(ii) positive and uniformly distributed over the surface of sphere 

(iii) negative and appears at a point the surface of sphere closest to point charge. 

(iv) Zero

(iv) Zero

Explanation:

Consider an uncharged conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then Zero.
As the sphere is isolated, so the total charge on it will remain same, which is zero.Presence or absence of any external charge nearby cannot change its total charge.
