Physics And Measurement Question 74
Question: Dimensional formula of capacitance is
[CPMT 1978; MP PMT 1979; IIT 1983]
Options:
A) $ c^{2}g^{0}{{p}^{-2}} $
B) $ ML^{2}T^{4}{{A}^{-2}} $
C) $ ML{{T}^{-4}}A^{2} $
D) $ {{M}^{-1}}{{L}^{-2}}{{T}^{-4}}{{A}^{-2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
[C] = $ ( \frac{Q}{V} )=( \frac{Q^{2}}{W} )=[ \frac{A^{2}T^{2}}{ML^{2}{{T}^{-2}}} ]=[{{M}^{-1}}{{L}^{-2}}T^{4}A^{2}] $
