Question

Q. The dimensional formula of electric potential is
A \(\left[M L^{2} T^{-3} A^{-1}\right]\)
B \(\left[M^{-1} L^{2} T^{-2} A\right]\)
c \(\left[M^{-1} L^{2} T^{-2} A^{-1}\right]\)
D \(\left[M L^{2} T^{-2} A\right]\)

Answer 1

Solution:
Electric potential,
$$
\begin{aligned}
&V=\frac{W}{q}=\frac{\left[M L^{2} T^{-2}\right]}{[A T]} \\
&=\left[M L^{2} T^{-3} A^{-1}\right]
\end{aligned}
$$
