Assuming force, length, and time to be the fundamental quantities, determine the dimensions of momentum.

Options

  1. AF^2T
  2. BFT⁻¹
  3. CFT
  4. 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 .
