Question

What formula gives the strength of an electric field, E, at a distance from a known source change?

A) E= Fe/qd
B) E= kq/d
C) E= kq/d^2
D) E= Fe/d

Answer 1

C) E= kq/d^2

Hoped this helped

Answer 2

The correct answer option is C. E = kq / d^2

Step-by-step explanation:

Electric field strength is a vector quantity which means it has both the magnitude and a direction.

It can be defined as the strength of electrical force per unit charge at any given point in the electric field and can be denoted by E.

Therefore, the formula for the electric field strength is:

E =
`(k .Q )/(d^2)`
