Physics And Measurement Question 45

Question: If $ C $ and $ R $ represent capacitance and resistance respectively, then the dimensions of $ RC $ are

[CPMT 1981, 85; CBSE PMT 1992, 95; Pb. PMT 1999]

Options:

A) $ M^{0}L^{0}T^{2} $

B) $ M^{0}L^{0}T $

C) $ M{{L}^{-1}} $

D) None of the above

Show Answer

Answer:

Correct Answer: B

Solution:

$ RC=T $ ∵ $ [R]=[ML^{2}{{T}^{-3}}{{I}^{-2}}] $ and $ [C]=[{{M}^{-1}}{{L}^{-2}}T^{4}I^{2}] $
