How do the Coulomb and Biot-Savart fields both depend on distance?
ABoth fall off as 1/r^3
BBoth rise with r
CBoth fall off as 1/r
DBoth fall off as 1/r^2
Answer & Solution
Correct answer: D. Both fall off as 1/r^2
Both laws are long range, with strength falling as the inverse square of the distance.
