Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases. And by whatever factor the distance is changed, the electric field strength
will change inversely by the square
of that factor.
What happens to the electric field if the distance is doubled?
Charge is a basic property of matter. Every constituent of matter has an electric charge with a value that can be positive, negative, or zero. … Therefore, if the distance between the two charges is doubled,
the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value
.
How would the electric field strength change when the distance from the charge is doubled?
It means that by doubling both the test charge Q and the distance between the charges, the net effect on the electric field strength is
its value being halved or its magnitude is reduced to one-half of its original value
. Doubling the distance d will reduce E to one-fourth of its original value.

How do you find the strength of an electric field?
The SI unit of electric field strength is newtons per coulomb (N/C) or volts per meter (V/m). The force experienced by a very small test charge q placed in a field E in a vacuum is given by
E = F/q
, where F is the force experienced.
What happened to the voltage between the plates when the separation was increased?
The voltage increases when the plate separation is increased. It is most likely because of the distance. The charge has to cover a bigger distance if the distance is larger. This means that there will be a decrease in the total capacitance.

Does current decrease with distance?
Whether the voltage is high or low, the force will transfer the same way. But
voltage will drop over distance
. Larger conductors can be used to compensate for voltage drop over long distances. Circuits with higher voltage also diminish voltage drop by reducing the current, thereby reducing I-squared-R losses.
How do the field lines show the field is stronger near the electrodes?
The direction of the field line at a point is the direction of the field at that point. The relative magnitude of the electric field is proportional to the density of the field lines.
