Four charges 2 C ,-3 C , 4 C ,-4 C and -1 C are enclosed by the Gaussian surface of radius 2 m . Net outward flux through the Gaussian surface is (in V - m ) [ ₀= . permittivity of free space ]
Options
- A2 ₀
- Bzero
- C3 ₀
- D5 ₀
Correct answer
A. 2 ₀
Step-by-step solution
The net outward flux through the Gaussian surface is determined by the net enclosed charge Q_ enc using Gauss's Law: = Q_ enc / ₀ . The enclosed charges sum to: q_i = 2 - 3 + 4 - 4 - 1 = -2 , C . This yields = -2 , C / ₀ . Since the net flux is outward by convention, the magnitude 2 , C / ₀ corresponds to option A .
