Question:
You are on vacation in an alternate universe where nearly all the laws of physics are the same as in your home universe, but you notice that the charge on an electron in the alternate universe is -0.9999e and the charge on a proton is +e. Consider now two spheres of copper, each with mass 1.0 kg.
(a) What is the total charge on one of the spheres?
(b) What is the electric force between the two spheres when they are separated by a distance of 0.50 m? Is this force attractive or repulsive?
(c) Compare the magnitude of the electric force with the magnitude of the gravitational force between the two spheres.
Step by Step Answer:
a Recognize the principle Since we know the total mass of each copper sphere and the molecular mass of copper we can determine the number of moles and ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
