Question

Transcribed Image Text:At what distance of separation must two 4.00 μC charges be positioned in order for the repulsive force between them to be equivalent to the weight (on Earth) of a 2.00-
kg mass?
Note: The formula for the force of gravity (weight) is F = mg where m = mass in kg and g = gravitational acceleration = 9.81 m/s^2.
