Point charge 3.5
μc
is located at
x
= 0,
y
= 0.30
m
, point charge -3.5
μc
is located at
x
= 0
y
= -0.30
m
. what are (a)the magnitude and (b)direction of the total electric force that these charges exert on a third point charge
q
= 5.0
μc
at
x
= 0.40
m
,
y
= 0?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the force on the thing and the distance the force moves the thing

your answer is, orbit around the nucleus
