Concepts Of Physics MCQ Edition [Volume 1]PhysicsIntroduction to Physics
Assuming force, length, and time to be the fundamental quantities, determine the dimensions of momentum.
Options
- AF^2T
- BFT⁻¹
- CFT
- DFLT⁻¹
Correct answer
C. FT
Step-by-step solution
The dimensional formula for momentum is [p] = MLT⁻¹ . The dimensional formula for force is [F] = MLT⁻² . We can express the dimensions of momentum as [p] = (MLT⁻²) T . Substituting the fundamental quantity force F and time T , we get [p] = FT .
