A thin metallic spherical shell of radius R carries a charge Q on its surface. A point charge `(Q)/(2)` is placed at the centre C and another charge `+2Q` is placed outside the shell at A at a distnace x from the centre as shown in the figure.
Find the electric flux through the shell.

Text Solution

Verified by Experts

Electric flux `phi=("Total enclosed charge")/(epsi_(0))`
Net chage enclosed inside the shell `q=0`
`:.` electric flux through the shell `(q)/(epsi_(0))=0`
