A, B, C , and D are four different physical quantities having different dimensions. None of them is dimensionless. But we know that the equation AD=C ln( BD ) holds true. Then which of the combination is not a meaningful quantity?
  1. CBD-A2D2C
  2. A2-B2C2
  3. AB-C
  4. A 2 −AC D

Solution

The dimension of A is not equal to the dimension of C

Hence it is not possible to subtract AC from A2
