Direction: Solve the following problems using the Coulomb's Law. Show your complete solutions. 1. Two equal point charges of +3.00 x 106 C are placed 0.200 m apart What are the magnitude and direction of the force each charge exerts on the other? 2. At what distance would the repulsve force between two electrons have magnitude 2.00 N? Between two protons? 3. A negative charge of- 0.550 µC exerts an upward 0.200 N force on an unknown charge 0.300 m directly below it (a) What is the unknown charge? (b) What are the magnitude and directions of the force that the unknown charge exerts on the – 0.550 µC charge? 4. Two small plastics spheres are given positive electrical charges. When they are 15.0 cm apart, the repulsive force between them has magnitude 0.220 N. What is the charge on each sphere (a) if the two charges are equal? (b) if one sphere has four times the charge of the other? 5. Two point charges are located on the y-axis as follows: q = -1.50 nC at y = -0,600 m, and charge q2 = +3.20 nC at the origin (y = 0). What is the net force (magnitude and direction) exerted by these two charges on a third charge q3 = +5.00 nC located at y = - 0.400 m?
