Solved: PHYSICS Question for NEET

NEET PHYSICSEasy

Dimensions of charge are:

$[M^0L^0T^{-1}A^{-1}]$

$[MLTA^{-1}]$

$[T^{-1}A]$

$[TA]$

Definition of Charge: Electric current ( $I$ ) is defined as the rate of flow of electric charge ( $Q$ ) over time ( $t$ ). $I = \frac{Q}{t} \implies Q = I \times t$
Identify Fundamental Dimensions: The fundamental dimension for electric current is $[A]$ (Ampere), and for time, it is $[T]$ .
Calculate Dimensions: Substituting the fundamental dimensions into the formula for charge: $[Q] = [A] \times [T] = [TA]$ Therefore, the dimensional formula for charge is $[M^0L^0TA]$ or simply $[TA]$ .
