Find the number of atoms in a nickel coin. A nickel coin has a mass of about 5 g. Each mole (6.02 1023 atoms) has a mass of about 58 g.
A positive charge with charge Q is placed at the origin. A negative charge with charge –Q is placed on the x-axis at a position of x = +d from the origin. If the magnitude of electrostatic force between the two charges is 1.02uN, answer the following question: Find the magnitude of the total force in units of uN on the positive charge at the origin if an additional charge with charge 2Q is placed along the y-axis at a...
The drawing shows a positive charge ( q 1 ) and a negative charge ( q 2 ) fixed to a circle. At the center of the circle they produce a net electric field that is directed along the horizontal axis. Determine the ratio q 1 / q 2 of the charges if α=32.0° and β=57.0°.
