`E_z = (k* "Q" )/ "L" (1/( "d" - "L" /2)-1/( "d" + "L" /2))`

Enter a value for all fields

The total field along axis is calculated using the following formula:  `E_z= (kQ)/L(1/(d-L/2)-1/(d+L/2))` where:

• `E_z` = total field along axis
• `k` = Coulomb's Constant (
• `Q` = charge
• `L` = unit length
• `d` = distance
