Measurement

The physical quantities not having same dimensions are

  1. torque and work
  2. stress and Young's modulus
  3. speed and (μ0ε0)–1/2
  4. momentum and Planck's constant

Answer

[Momentum] = [MLT–1]

[Planck's constant] = [ML2T–1]

Momentum and Planck's constant do not have same dimensions.

The correct option is D.
