MHT CET2010PhysicsUnits and Dimensions
The dimensions of Planck's constant is the same as the product of
Options
- Aforce and time
- Bforce, displacement and time
- Cforce and distance
- Dtime and displacement
Correct answer
B. force, displacement and time
Step-by-step solution
The dimensions of Planck constant, [h]= [ E v ]= [ ML ² ~T ⁻¹ ] Force, [F]= [ MLT ⁻² ] Displacement, [d]=[ L ] Time [t]=[ T ] [F][d][t]= [ MLT ⁻² ][ L ][ T ] = [ ML ² ~T ⁻¹ ] Hence the dimensions of Planck's constant is the same as the product of force, displacement and time.
