If the separation between the charges is increased then the magnitude of the force will increase in fact how the distance is being used in that formula.
The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:

where Q is the charge and

is the time. Re-arranging the formula, we have

for the compressor in our problem, the intensity of current is I=66.1 A, while the time is

, so the amount of charge that crosses a certain point of the circuit during this time is
The Correct answer to number 1 is A or D
The correct answer to number 2 is C because transmission meaning is to travel.
PS. I think number 1 is D
