Question
Suppose A = BC, where A has the dimension L/M and C has the dimension L/T. Then B has the dimension:
Correct Answer
Option A is the correct answer.
Detailed Explanation
A = BC → B = A/C. Dimensions: [A] = L/M, [C] = L/T. So [B] = (L/M) / (L/T) = (L/M) × (T/L) = T/M.
Hint
Divide dimensions: [B] = [A]/[C].
