    In the following list, the only pair which have different dimensions, is                          [Manipal MEE 1995]

    A)             Linear momentum and moment of a force

    B)             Planck's constant and angular momentum

    C)             Pressure and modulus of elasticity

    D)             Torque and potential energy

    Correct Answer: A

    Solution :

                    Linear momentum = Mass \[\times \] Velocity = \[[ML{{T}^{-1}}]\] Moment of a force = Force \[\times \] Distance = \[[M{{L}^{2}}{{T}^{-2}}]\]
