What is the electric flux for Gaussian surface A that encloses the charged particles in free space? [Given: q 1 = - 14 nC , q 2 = 78 . 85 nC , q 3 = - 56 nC

Options

  1. A10 3   N   m 2   C - 1
  2. B10 3   C   N - 1   m - 2
  3. C632 × 10 3   N   m 2   C - 1
  4. D632 × 10 3   C   N - 1   m - 2

Correct answer

A. 10 3   N   m 2   C - 1

Step-by-step solution

Using Gauss theorem of electrostatics, the electric flux is ϕ = q ε 0 Net charge enclosed by the gaussian surface A is, q = q 1 + q 2 + q 3 ⇒ q = 8 . 85   nC Electric flux, ϕ = 8 . 85 × 10 - 9   C 8 . 85 × 10 - 12   C 2   N - 1   m - 2 = 10 3   N   m 2   C - 1
