Question
Figure shows a closed surface which intersects a conducting sphere. If a positive charge is placed at the point P, the flux of the electric field through the closed surface:
Options
A.will become positive
B.will remain zero
C.will become undefined
D.will become negative
Solution
enclosed charge = +ve ⇒ flux through closed surface = +ve.
⇒ Due to induction the charge enclosed in the dotted becomes +ve
