Physics Question on Electric charges and fields
Figure below 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
A
will remain zero
B
will become positive
C
will become negative
D
will become undefined
Answer
will become positive
Explanation
Solution
The positive & negative charges developed on different parts of conducting sphare due to induction. Hence the flux through the closed surface is positive.
