A long straight horizontal wire carries a current I = 1.80 A to the left. A positive 1.00 C charge moves to the right at a distance 5.00 m above the wire at constant speed v = 1250 m/s . (Figure 1) What are the magnitude and the direction of the magnetic force on the charge?

If the charge were located a distance 10.0 m from the wire, how would the net magnetic force on the charge compare to that found above?

The force would be one-fourth as great.

The force would be one-half as great.

The force would be the same.

The force would be double.

The force would be quadruple.
