A metallic sphere of radius R carrying a charge q is kept at certain distance from another metallic sphere of radius R / 4 carrying a charge Q . What is the electric flux at any point inside the metallic sphere of radius R due to the sphere of radius R / 4 ?

Options

  1. AQ ₀ - q ₀
  2. BZero
  3. Cq ₀ - Q ₀
  4. DQ ₀

Correct answer

B. Zero

Step-by-step solution

Since spheres are electrostatically shielded from each other, =0 .
