  1. 3μC 40g 3μC 40g 50cm Problem # 1 Two 40 gram masses each with a charge of 3μC are placed 50cm apart. Compare the gravitational force between the two masses to the electric force between the two masses. (Ignore the force of the earth on the two masses)

  2. The electric force is much greater than the gravitational force.

  3. Problem 2 - 5μC 45º - 4μC 5μC 20cm F1 45º F2 20cm Three charged objects are placed as shown. Find the net force on the object with the charge of -4μC. F1 and F2 must be added together as vectors.

  4. - 2.9 F1 - 1.6 45º 3.31 F2 + 2.3cos45≈1.6 θ 29º 2.3sin45≈1.6 F1 = < - 4.5 , 0.0 > F2 = < 1.6 , - 1.6 > Fnet = < - 2.9 , - 1.6 > 3.31N at 209º
