The force between two charges is proportional to the product of the charges.
If only one of the charges is reduced by a factor of 3, then the force is reduced by a factor of 3.
If both charges are reduced by a factor of 3, then the force is reduced by a factor of 9.
In order to change the colour of the light, you would need to change both the wavelength and frequency of light, as light in the visible spectrum, have their own unique wavelengths that they occur in along with the measure of frequency, which measures the number of cycles or turns a wave can occur from trough to trough or crest to crest within a given period of time.

The first moment of the total cross sectional area taken about the neutral axis must be zero.
As with non-composite beams, the neutral axis (NA) is the location where the bending stress is zero. The location of the NA depends on the relative stiffness and size of each of the material sections.
Generally, the NA location is determined relative to the bottom surface of the beam. However, this is not mandatory, and the location can be relative to any location. If the bottom is used, then the NA axis is a distance "h"
The distance h can be determined by recalling that the stresses through the cross section must be in equilibrium.

B, each color has a different wavelength and that allows the eye to see each color different
