EXPLANATION
Question: What is the dimension of work?
- a) MLT⁻²
- b) ML²T⁻²
- c) MLT⁻¹
- d) ML⁻²T⁻²
ANSWER: b) ML²T⁻²
EXPLANATION:
The dimension of work is given by the product of the dimensions of force and displacement. The dimension of force is represented by [M L T^(-2)] (mass times length divided by time squared), and the dimension of displacement is represented by [L] (length). Multiplying these dimensions together gives us:
[MLT⁻²] * [L] = [ML²T⁻²]
Therefore, the correct option for the dimension of work is (b) ML²T⁻².
