Question: What are the dimensions of acceleration?
- a) M⁻¹LT⁻¹
- b) M⁻¹L⁻¹T⁻²
- c) M⁻²L⁻¹T⁻²
- d) M⁰LT⁻²
ANSWER: d) M⁰LT⁻²
EXPLANATION:
The answer is (d) M⁰LT⁻².
Acceleration is the rate of change of velocity with respect to time. Velocity has the dimensions of L/T and time has the dimensions of T. Therefore, the dimensions of acceleration are L/T², which can also be written as M⁰LT⁻².
Therefore, the correct option for the dimension of work is (a) ML²T⁻².
