Coulomb's Law: Beyond the Fundamentals
Printer Friendly Version
In this lesson we will look at more advanced problems beyond the basic proportional relationships we have already studied using Coulomb's Law,
.
Refer to the following information for the next three questions.
Three point charges are placed along the x-axis. A +5 µC charge is located at the origin, a +2 µC charge is located 30 cm to its right, and a -4 µC is located at 50 cm.
Calculate the magnitude and direction of the force exerted on the +2 µc charge by the +5 µC charge.
Calculate the magnitude and direction of the force exerted on the +2 µc charge by the -4 µC charge.
What is the magnitude and direction of the net force on the +2 µC charge?
Refer to the following information for the next four questions.
Two point charges are placed along the x-axis. A +5 µC charge is located at the origin and a -4 µC is located at 50 cm. Our task is to determine where the +2 µC charge could be placed so as to feel no electrostatic force.
Why should the +2 µC charge be placed to the right of the -4 µC charge and not to the left of the +5 µC charge?
Develop and expression for the magnitude of the force exerted on the +2 µc charge by the -4 µC charge.
Develop an expression for the magnitude of the force exerted on the +2 µc charge by the +5 µC charge.
What value(s) of x will place the +2 µC charge in equilibrium?
Refer to the following information for the next six questions.
Examine the following diagram which shows four charges that have been placed on the corners of a square 50 cm on each edge. Our task is to determine the net force on the 2 µC charge.
Sketch in the forces acting on the 2 µC charge.
