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 figure. The three charges are positive. Then choose the incorrect option

Options:

the net force on q is zero

the force on q due to q1 is $\frac{1}{4 \pi \varepsilon_0} \frac{qq_1}{d^2}$ towards left

the force on q due to Q is zero

the force on q due to shell (induced charge) is zero

Correct Answer:

the force on q due to shell (induced charge) is zero

Explanation:

Use the concept of Coulomb’s law.
