Question

If the strength of the magnetic field at A is 48 units and the strength of the magnetic field at B is 3 units, what is the distance to B? (Drawing is not to scale!) 400 m 25 m 80 m 20 m

Answer 1

20m

Step-by-step explanation:

Answer 2

This is the formula to calculate the distance:

Force (F)= charge (q) * velocity (v) * field strength (B)

In the end, you get 20 units, which should be the correct answer.
