Question

Two spheres of radii R subscript 1 and R subscript 2 joined by a fine wire are raised to a potential V. Let the surface charge densities at these two spheres be sigma subscript 1 and sigma subscript 2 respectively. Then the ratio sigma subscript 2 over sigma subscript 1 has a value

  1. R subscript 1 over R subscript 2
  2. R subscript 2 over R subscript 1
  3. 1
  4. open parentheses R subscript 2 over R subscript 1 close parentheses squared

The correct answer is: R subscript 1 over R subscript 2
