Question

The dimensional formula of electric intensity is

• A. $\lbrack M^{1}L^{1}T^{3}A^{- 1}\rbrack$
• B. $\lbrack ML^{- 1}T^{3}A^{1}\rbrack$
• C. $\lbrack M^{1}L^{1}T^{- 3}A^{- 1}\rbrack$
• D. $\lbrack M^{1}L^{2}T^{1}A^{1}\rbrack$

Answer 1

Answer: (C)

$\lbrack M^{1}L^{1}T^{- 3}A^{- 1}\rbrack$

Answer 2

: From $E = \frac{F}{q}$ $= \frac{\lbrack M^{1}L^{1}T^{- 2}\rbrack}{\lbrack AT\rbrack} = \lbrack M^{1}L^{1}T^{- 3}A^{- 1}\rbrack$
