At what value of y should a group of 3 electrons be placed such that its electrostatic force on the first electron balances the gravitational force on the first electron?

Four identical charged particles (q +10.4 pC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L 54.6 cm and W 14.7 cm L W (a) Calculate the magnitude of the total electric force exerted on the charge at the lower left corner by the other three charges. N (b) Calculate the direction of the total electric force exerted on the charge at the lower left corner by the other three charges. (counterclockwise from the x-axis)

Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.113 N when their center-to-center separation is 45.4 cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.0532 N. Of the initial charges on the spheres, with a positive net charge, what was (a) the negative charge on one of them and (b) the positive charge on the other? (Assume the negative charge has smaller magnitude.) Units (a) NumberT-0.05097 (b) NumberTo.04506 UnitsTc

Two chloride ions and two sodium ions are in water, the “effective charge” on the chloride ions (Cl−) is −2.00 × 10−21 C and that of the sodium ions (Na+) is +2.00 × 10−21 C. (The effective charge is a way to account for the partial shielding due to nearby water molecules.) Assume that all four ions are coplanar.             where a = 0.280 nm, b = 0.760 nm, and c = 0.460 nm.         What is the direction of electric force on the chloride ion in the lower right-hand corner in the diagram? Enter the angle in degrees where positive indicates above the negative x-axis and negative indicates below the positive x-axis.   °         Prev
