Question
The dimensional formula for ab/RT is:
Correct Answer
Option A is the correct answer.
Detailed Explanation
[a] = ML⁵T⁻², [b] = L³, so [ab] = ML⁸T⁻². [RT] = ML²T⁻². So [ab/RT] = ML⁸T⁻² / ML²T⁻² = L⁶. That is not matching any? L⁶ is volume squared. But option A is MLT⁻², which is force. Possibly misprint. Given answer A, we'll note the inconsistency.
Hint
Compute dimensions of a, b, R, T and then divide.
