medium MCQ Class 12 · Physics · Semiconductor Electronics Materials Devices and Simple Circuits
  1. It follows an inverse-square law relationship or dipolar
  2. It increases linearly with increasing distance
  3. It remains strictly constant at all spatial coordinates
  4. It varies exponentially as
Answer
It follows an inverse-square law relationship or dipolar

The correct answer is It follows an inverse-square law relationship or dipolar — Dipole configurations decrease faster () due to opposite charge cancellation.

Step-by-step solution

  1. Point charges/sources produce inverse-square fields ().
  2. Dipole configurations decrease faster () due to opposite charge cancellation.

Concept tested: Spatial Distance Dependence
