Physics And Measurement Question 246
Question: Let Q denote the charge on the plate of a capacitor of capacitance C. The dimensional formula for $ \frac{Q^{2}}{C} $ is
Options:
A) $ [L^{2}M^{2}T] $
B) $ [LMT^{2}] $
C) $ [L^{2}M{{T}^{-2}}] $
D) $ [L^{2}M^{2}T^{2}] $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] We know that $ \frac{Q^{2}}{2C} $ is energy of capacitor, so it represent the dimension of energy $ =[ML^{2}{{T}^{-2}}] $
