Physics And Measurement Question 187
Question: If $ F=\frac{v}{C\ln (xb)} $ , then
Options:
A) F and v denote force and velocity, the dimensions of C are [MT]
B) x denotes distance, the dimensions of b are [ $ L _{{}}^{-1} $ ]
C) The dimension of $ \frac{v}{C} $ never be same as F
D) The dimensions of x must be same as $ \frac{v}{cb} $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Logarithm has no dimensions. $ [xb]=[M^{0}L^{0}T^{0}]=>[b]=[{{L}^{-1}}] $
Hence, option [b] is correct.
