Given below are two statements Statement I : An electric dipole is placed at the centre of a hollow sphere. The flux of electric field through the sphere is zero, but the electric field is not zero anywhere in the sphere. Statement II : If R is the radius of a solid metallic sphere and Q be the total charge on it. The electric field at any point on the spherical surface of radius r < R is zero but the electric fl

Options

  1. ABoth Statement I and Statement II are true
  2. BStatement I is false but Statement II is true
  3. CStatement I is true but Statement II is false
  4. DBoth Statement I and Statement II are false

Correct answer

C. Statement I is true but Statement II is false

Step-by-step solution

∮ E → · d s → = q in ε 0 = 0 = ϕ Flux of E → through sphere is zero. But ∮ E → · d s → = 0 ⇒ E → · d s → ≠ 0 for small section d s only Statement- 2 As change encloses within gaussian surface is equal to zero. ϕ = ∮ E → · d s → = 0
