The formula for calculating electric field strength is E = F/q, where E is the electric field strength, F is the force exerted by the electric field, and q is the charge of the object.
To convert Newtons per Coulomb to volts per meter, you can use the formula E = V/d, where E is the electric field strength in volts per meter, V is the voltage in volts, and d is the distance in meters.
To determine the direction of the electric field, you can use the right-hand rule. Point your thumb in the direction of the electric field, then curl your fingers. The direction in which your fingers curl is the direction of the electric field.
The SI unit for electric field strength is volts per meter (V/m).
The strength of an electric field is affected by the magnitude of the charge creating the field, the distance from the charge, and the medium in which the charge exists. Additionally, the presence of other charges can also affect the strength of the electric field.
