Question

Three physical quantity having dimensions [ M L^-1 T^-2] are.

• A. Stress, pressure, work
• B. Stress, pressure, coefficient of elasticity
• C. Stress, pressure, torque
• D. Stress, pressure, density

Answer 1

The correct option is B

Stress, pressure, coefficient of elasticity

Pressure = Force/Area = ML1T-2/ L2 = [M L-1 T-2]

Stress = Force/Area = ML1T-2/ L2 =[M L-1 T-2]

Coefficient of elasticity = Stress/strain = [M L-1 T-2]
