Electrostatics I
Ex 1: How many electrons must be removed from an electrically neutral silver dollar to give it a charge
of two micro coulombs (+2 x 10-6 C) ? [CutnellP18.1sim]
Ex 2: A single sphere has a positive charge of three micro coulombs (+3 μC). How many electrons must
the sphere gain so that the charge becomes negative two micro coulombs (-2 μC) ?
[CutnellP18.2sim]
Ex 3: A metal rod has a charge of +5 μC. What is the net charge after 3 x 1015 electrons have been
removed from it ? [CutnellP18.3sim]
Ex 4: Four identical metal spheres each carry different charges. The charges are +1.6 μC, + 6.2 μC,
-4.8 μC and -9.4 μC. These objects are brought simultaneously into contact, so that each touches
the others. Then they are separated. What is the final charge on each object ? [CutnelleEP18.4]
