Question

A thin, metallic spherical shell contains a charge Q on it. A point charge q is placed at the centre of the shell and another charge q1 is placed outside it as shown in the following  figure . All the three charges are positive. The force on the central charge due to the shell is

  •  towards left

  • towards right

  • upward

  • zero

Solution

towards right
This question can be answered using the concept of electric field lines.
We know that electric field lines emerge from a positive charge and move towards a negative charge. Now, charge Q, on the face in front of charge q1, tries to nullify the field lines emerging from charge q1. So, the charge on the farther face of the conductor dominates and, hence, a force appears to the right of charge q.

  Is there an error in this question or solution?
