In the following list, the only pair which have different dimensions,is
A
Linear momentum and moment of a force
B
Torque and potential energy
C
Planck's constant and angular momentum
D
Pressure and modulus of elasticity
Correct option is A. Linear momentum and moment of a force
Linear momentum is given as:
p=$$Mas \times Velocity =[MLT^{-1}]$$
Moment of a force is given as:
Moment =$$ Force\times Distance=[ML^2T^{-2}]$$
