JEE Main202529 Jan 2025Morning ShiftPhysicsUnits and DimensionsActual
The pair of physical quantities not having same dimensions is :
Options
- APressure and Young's modulus
- BSurface tension and impulse
- CTorque and energy
- DAngular momentum and Planck's constant
Correct answer
B. Surface tension and impulse
Step-by-step solution
[Angular momentum ]= ML ^2 ~T ⁻¹ [Planck's Constant] = ML ^2 ~T ⁻¹ [Torque] = ML ^2 ~T ⁻² [Energy] = ML ^2 ~T ⁻² [Surface tension] = MT ⁻² [Impulse]= MLT ⁻¹ [Pressure ]= ML ⁻¹ ~T ⁻² [Young's modulus] = ML ⁻¹ ~T ⁻²
