Electric Field Calculator
Top
The electric field of a electric charge is the space around the charge in which another charge experiences a force of repulsion or attraction. Electrc field calculator calculates either electrostatic force between the charges, charges or electric field if any two among the three are given.

## Step by Step Calculation

Step 1 :

Electric Field Formulas:

E = $\frac{F}{q}$

F = q * E

q = $\frac{F}{E}$

Where,

F = Force

E = Electric Field

q = Charge

Step 2 :

Put the values in the formula and calculate it further.

## Example Problems

1. ### Calculate the charge of electrons having electric field of 50 N/C and force of 40 N.

Step 1 :

Given:

E = 50 N/C

F = 40 N

Formula:

q = $\frac{F}{E}$

Step 2 :

Put the values in the formula and calculate it further.

E = $\frac{F}{q}$

q = $\frac{F}{E}$

= $\frac{40 N}{50 N/c}$

= 0.8 C

q = 0.8 C

2. ### The earth has a net charge that produces an electric field of 100 N/C at its surface in downward direction. Calculate the force produced by free electron near the earth's surface.

Step 1 :

Given:

E = 100 N/C

q = 1.6 * 10-19 C

Formula:

F = q * E

Step 2 :

Put the values in the formula and calculate it further.

E = $\frac{F}{q}$

F = q * E

= 100 * 1.6 * 10-19

= 160 * 10-19 N
