Physics And Measurement Question 154
Question: The dimensions of shear modulus are?
[MP PMT 2004]
Options:
A) $ ML{{T}^{-1}} $
B) $ ML^{2}{{T}^{-2}} $
C) $ M{{L}^{-1}}{{T}^{-2}} $
D) $ ML{{T}^{-2}} $
Show Answer
Answer:
Correct Answer: C
Solution:
Shear modulus = $ \frac{\text{Shearing stress}}{\text{Shearing strain }} $
$ =\frac{F}{A\theta }=[M{{L}^{-1}}{{T}^{-2}}] $
