14.2 | Coulomb's Law |
1) Two positive charges Q1 = 2.0 μC and Q2 are placed 4.0 m away from each other. As a result, a 0.008 N electrostatic force is produced between them. What is the magnitude of the charge Q2 in micro Coulombs?
Correct Answer: D
2) Three electric charges Q1 = 6 μC, Q2 = 1 μC and Q3 = 3 μC are collinear, as shown in the figure.
What is the magnitude of electrostatic force actin on Q3?
Correct Answer: C
3) Three electric charges are placed at the vertices of a right triangle as shown in the figure below.
What is the magnitude of resultant force acting on Q1 if the charges are: Q1 = 3 μC, Q2 = - 6 μC and Q3 = - 2 μC?
Correct Answer: A
