1) Coulomb's law is F = (kq₁9₂)/r² where k = 9 X 10° in Sl units. Suppose that q1 = 6 µC and q2 = 4 µC, and r = 25 cm, calc. the force between these particles. 2) The proton and electron in a H atom both have a charge of 1.6 X 10-1⁹ C They are r = 5 X 10-¹⁰0 meters apart. Calc. the force between them 3) If two charged pith balls have a force of F due to electrostatic attraction, what is the final force on them if the distance between them is doubled? (a) 2F (b) 4F (c) F/2 (d) F/4 4) A charge - 2 C is placed at the origin of the xy plane. A charge of 3 C is placed at x = 25 cm. A final charge of -8 C is placed at x = 50 cm. Calc. the force between the - 2 C and 3 C charges (this force will be in the positive x direction or +i) 5) In problem 4, calc. the force between the - 2 C and - 8 C charges. (this force will be in the negative x direction or i 6) To get the resultant force on the -2 C charge, add the two force vectors you calculated in problems 4 and 5. 1) Coulomb's law is F = (kq₁9₂)/r² where k = 9 X 10° in Sl units.
