Question

The dimensional formula of the ratio of electrical dipole moment to the magnetic moment is \(M^PL^Q T^RA^S.\) Then P, Q, R and S are

(1) 0, -1, 1, 0

(2) 0, 1, -1, 0

(3) 0, 1, 0, -1

(4) 0, 1, 0, 1

Answer 1

Correct option is : (1) 0, -1, 1, 0

\(\left[\frac{P}{M}\right] = \left[ \frac{B}{E}\right] = \left[ \frac{1}{C}\right] = M^0L^{-1} T^1A^0\)
