If the magnitude of intensity of electric field at a distance ' r ₁ ' on an axial line and at a distance ' r₂ ' on an equatorial line due to a given short dipole are equal, then r₁: r₂ , is
Options
- A[3] 2 : 1
- B2 : 1
- C1: 2
- D1: [3] 2
Correct answer
A. [3] 2 : 1
Step-by-step solution
aligned & E_ axial =E_ equatorial k 2 p r₁^3 = k p r₂^3 & r₁ r₂ = 2^ 1 / 3 1 = [3] 2 : 1 aligned
