A positive point charge is placed at P in front of an earthed metal sheet S . Q and R are two points between P and S as shown in the figure. If the electric field strength at Q and R are respectively E Q , E R and potential at Q and R are respectively V Q , V R . Then

Options

  1. AE Q = E R
  2. BE Q < E R
  3. CV Q > V R
  4. DV Q < V R

Correct answer

C. V Q > V R

Step-by-step solution

As we are are moving away from P toward sheet S spacing between electric lines of force is increasing. ∴ E R < E Q In direction of electric field potential decreases. ∴ V R < V Q
