Question:

The dimensions of the quantity $\vec E × \vec B$ where $\vec E$ represents the electric field and $\vec B$ the magnetic field may be given as:

Options:

$MT^{–3}$

$M^2LT^{–5}A^{–2}$

$M^2LT^{–3}A^{–1}$

$MLT^{–2}A^{–2}$

Correct Answer:

$M^2LT^{–5}A^{–2}$

Explanation:

The correct answer is Option (2) → $M^2LT^{–5}A^{–2}$

$\vec E × \vec B→ (MLT^{–3}A^{–1}) × (MT^{–2}A^{–1}) = M^2LT^{–5}A^{–2}$.
