Question
A neutral spherical metallic object A is placed near a finite metal plate B carrying a positive charge. The electric force on the object will be :
Options
A.away from the plate B
B.towards the plate B
C.parallel to the plate B
D.zero
Solution

The given diagram shows induction on sphere (metallic) due to metal plate.
Since distance between plate and −ve charge is less than that between plate and +ve charge. electric force acts on object towards plate.
