Answer:

Hot (A)

Explanation:

because there are electrons going through there, the friction between the metallic nuclei and electrons creates vibrations known as heat.

if you touch it the electrons will run through your body and caus damadge.

If we assume that the metallic plates are perfect conductors, the electric field in their interiors must vanish. given that the

Svetlanka [38]

here the charge density of metal plate is given as

$charge density = \sigma$

now the electric field is given Gauss law

$\int E. dA = \frac{q}{\epsilon_0}$

now here E = constant

so we will have

$E. \int dA = \frac{q}{\epsilon_0}$

Since total area on both sides of plate will be double and becomes 2A

$E. 2A = \frac{q}{\epsilon_0}$

$E = \frac{q/A}{2\epsilon_0}$

$E = \frac{\sigma}{2\epsilon_0}$

Now if we will find the electric field inside the metal plate

Then as we know that total charge inside the plate will always be zero

so we have

$E = 0$
