A) Force, momentum and power
B) Impulse and momentum
C) Work, couple and power
D) Pressure, force and stress
Correct Answer: B
Solution :
Impulse =Force \[\times \]Time Dimensional formula is given by [lmpluse] = [Force]\[\times \][Time] \[=[ML{{T}^{2}}]\times [T]\] \[=[ML{{T}^{-1}}]\] Momentum = Mass\[\times \]Velocity Dimensional Formula is given by [Momentum] = [Mass]\[\times \][Velocity] \[=[M][L{{T}^{-2}}]\] \[=[ML{{T}^{-1}}]\] \[\therefore \] Both momentum and impulse have same dim dimensional formula.
