Question: The dimensions of couple are
[CPMT 1972; JIPMER 1993]
Options:
A) $ ML^{2}{{T}^{-2}} $
B) $ ML{{T}^{-2}} $
C) $ M{{L}^{-1}}{{T}^{-3}} $
D) $ M{{L}^{-2}}{{T}^{-2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Couple = Force $ \times $ Arm length = $ [ML{{T}^{-2}}][L]=[ML^{2}{{T}^{-2}}] $
