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
