Two electrons in a vacuum are spaced apart by the width of a human hair. a) Are the electrons repelled or attracted by each other? b) Sketch the shape of the electric field lines around the electrons. Include arrows indicating the field direction. c) Using Coulomb's law and a Coulomb's constant of k=8.99x 10' N.mc calculate the force between them. What happens to the force if the distance between them is tripled? [Hairs of course come in all sorts of diameters - but in this case use 50 pm - 5 x 10 m] 4. A rechargeable Li-ion battery is rated as having a capacity of 9900 mAhr. a) How many Coulombs of charge can it supply? b) How many electrons is that?
