Electrostatic force – problems and solutions
What attractive forces would act on each bundle? The number of moles of copper is Thus we have. This is an enormous charge.
When two objects are rubbed with each other, approximately a charge of 50 nC can be produced in each object. Calculate the number of electrons that must be transferred to produce this charge. Ans: The total number of electrons in the human body is typically in the order of 10 Calculate the electrostatic force between you and your friend separated at a distance of 1m. Compare this with your weight.
Do you have questions? If you feel that you have mastered these topics through the work you did in Physics 1, you do not need to work these problems. A second charge q 2 has a magnitude of Determine the electrostatic force each charge exerts on the other. It is used to detect the presence of excess charge. The top of the electroscope is made of a metal ball a conductor.
