Electric Charges and Forces Principles
An electron and a proton are separated by 1.50 X 10^-10 m. If they are released, which one will accelerate at a greater rate, and what is the magnitude of that acceleration?
Calculate the ratio of the electric force to the gravitational force between an electron and a proton.
Why do the two leaves of a neutral electroscope go apart when a positive rod is brought near the cap (but not touching it)?
There are four charged objects: A, B, C, and D. Object A is charged positively. Object A is attracted to Object B. Object B is repelled from Object C. Object C is attracted to Object D. What are the charges on Objects B, C, and D?
Two small, identical, charged spheres attract each other with a force of 8.0 x 10-5 N, when they are 30 cm apart. They are touched together, and are again placed 30 cm apart, but they now exert a force of repulsion of 1.0 x 10-5 N on each other. What is
One 24-g conducting pith ball has -6.4 µC of charge and touches an identical pith ball that is initially neutral. The diagram below (not to scale) shows the final configuration of the two pith balls as they hang from threads:- Explain the value of the cha
Three objects carrying charges of -4.0 x 10-6 C, +6.0 x 10-6 C, and +9.0 x 10-6 C, respectively, are placed in a line, equally spaced from left to right by a distance of 0.50 m. Calculate the magnitude and direction of the net force acting on each that r
Each corner of a right angled triangle is occupied by identical point charges "A", "B", and "C" respectively. Draw a sketch of this arrangement. "A" exerts force F on "B". An equal force F is exerted by "C" on "B" (deltaABC=90 degrees). Determine an expre
Paper is considered an insulator. How does a positively charged piece of tape pick up a neutral paper bit?
A negative object is brought near the left side of a conducting sphere but does not touch it. Meanwhile, a person briefly touches the right-hand side of the sphere. What happens to the sphere in this process?
