Determine the dimensions of linear momentum.

Options

  1. AMLT⁻¹
  2. BML^2T⁻¹
  3. CML^2T⁻²
  4. DMLT⁻²

Correct answer

A. MLT⁻¹

Step-by-step solution

Linear momentum is defined as the product of mass and velocity. p = m v The dimensional formula for mass is [M] . The dimensional formula for velocity is [LT⁻¹] . Substituting these dimensions, we get the dimensional formula for linear momentum: [p] = [M] [LT⁻¹] = [MLT⁻¹]
