Which of the following is the dimensional formula for electric polarisation?

Options

  1. AM 0 L - 2 T 1 I 1
  2. BM - 1 L - 2 T 1 I - 1
  3. CM 0 L - 1 T 1 I 1
  4. DM 1 L - 2 T 1 I 1

Correct answer

A. M 0 L - 2 T 1 I 1

Step-by-step solution

Electric polarisation (P) is given by P = ε 0 χ E where, E is electrical field and χ is electric susceptibility and it is dimensionless quantity, Dimension formula of P = Dimension formula of ε 0 × Dimension formula of E = M - 1 L - 3 T 4 I 2 = M 0 L - 2 T 1
