Final answer:
To determine the maximum electric field from a point light source at a distance of 9.1 m, additional information is needed.
Step-by-step explanation:
The maximum electric field from a point light source can be determined using the inverse square law. According to this law, the electric field decreases with the square of the distance from the source. Therefore, to find the maximum electric field at a distance of 9.1 m, you need to know the electric field at a shorter distance.
Without this information, it is not possible to determine the maximum electric field at 9.1 m from a point light source. Additional details or conditions are needed to calculate the electric field.
If you can provide more information, I would be happy to help you calculate the maximum electric field.
