The dimensions of weight are:
Correct answer: B. ML T-2
- A. ML T-1
- B. ML T-2
- C. LT-2
- D. ML2T
Explanation
The following is the solution: Weight (W) = Mass × Acceleration . . . . . . (1) Since, Acceleration = Velocity × [Time]-1 And, velocity is dimensionally represented as [M0 L1 T-1] ∴ The dimensional formula of acceleration = [M0 L1 T-2] . . . . . (2) The dimensions of mass = [M1 L0 T0] . . . . (3) On substituting equation (2) and (3) in equation (1) we get, Weight = Mass × Acceleration Or, W = [M1 L0 T0] × [M0 L1 T-2] = [M1 L1 T-2].
