Question

An electric field always surrounds ________.
Group of answer choices

uncharged particles

negatively and positively charged particles

only positively charged particles

only negatively charged particles A

Answer 1

An electric field always surrounds negatively and positively charged particles

Explanation:

Any electric charge produces an electric field around itself.

The magnitude of the electric field produced by a single-point charge is given by the equation:

$E=k\frac{q}{r^2}$

where

k is the Coulomb's constant

q is the magnitude of the charge

r is the distance at which the field is calculated

The electric field has a radial shape and follows an inverse square law, with the magnitude decreasing as we move away from the charge.

Also, the direction of the field is as follows:

• The field points away from the charge if the charge is positive
• The field points towards the charge if the charge is negative
