The force of repulsion between two like-charged particles will increase if

a) the distance between the charged particles is increased.

b) the distance between the charged particles is decreased.

c) the magnitude of the charge on both the particles is decreased.

d) the magnitude of the charge on one of the particles is decreased.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
