If same charge q is placed inside a sphere and cube having radius 1 m and side 2 m respectively. What will be the ratio of flux passing through them?

Options

  1. A1: 1
  2. B1: 8
  3. C8: 1
  4. D1: 2

Correct answer

A. 1: 1

Step-by-step solution

According to Gauss's law, electric flux passing through a closed surface is equal to 1 ₀ times the charge (q) enclosed by the surface i.e. = q ₀ Since, cube and sphere, both enclose same charge, therefore flux passing through cube and sphere is same. i.e. _ sphere = _ cube _ sphere : _ cube =1: 1
