A helium atom has two protons in its nucleus. If the attractive force between an orbital electron and the nucleus is 4.8 X 10^-7 N, what is the atomic radius of a helium atom?
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
Why do the two leaves of a neutral electroscope go apart when a positive rod is brought near the cap (but not touching it)?
Three charges are shown in the diagram below:- Construct a diagram showing arrows that represent the forces on the -3.2 µC charge.- Calculate the net force on the -3.2 µCcharge.- If the -3.2 µCcharge has a mass of 75 grams, calculate its initial accelerat
Two protons are 1.0 µm apart. What is the electric force between them?
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
Two pith balls each hang from a thread and are suspended from the same hook. If each pith ball is charged -6.4 X 10^-5 C and they are separated by a distance of 0.56 cm, what is the force between them?
Two small charges +4.0 x 10-5 C and -1.8 x 10-5 C, are placed 24 cm apart. What is the force on the third small charge, of magnitude -2.5 x 10-6 C, if it is placed on the line joining the other two and
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
What can be said about a sphere that has a net charge of +4.0 X 10^-15 C?
