1) consider two charges q1 =3 uc and q2=-2 uc,
a) state whether the electric force between these charges is attractive ore repulsive
b) what happens to the electric force if the distance between the charges is double (multiplied by two).
2) if the current through a resistor is 5mA. how many coulombs of charge flow through this resistor in one minute?
1 answer
The attract, if distance is doubled, attraction is 1/4th what it was.
