PhysicsNEET 2023Electric flux and Gauss's law with applications

Electric Charges and Fields

If over a surface, then:

  1. A.The number of flux lines entering the surface must be equal to the number of flux lines leaving it✓
  2. B.The magnitude of the electric field on the surface is constant
  3. C.All the charges must necessarily be inside the surface
  4. D.The electric field inside the surface is necessarily uniform

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
