Determine the electrostatic force using the Coulomb's Law equation and the Coulomb's Electrostatic Force Calculator Recall that 1 X 106 C = 1 µC. This means that one millionth of a coulomb of charge is equal to1 microcoulomb. F. elect d? 1. Two charged spheres with charges 2µC and 4 µC are separated by a distance of 3cm. a. Is the Electrostatic force repulsive or attractive? Explain

Identify the best method for finding the electric field strength at the test point, choosing from the following options A-E for each of the listed source configuration a-f. A. Coulomb's law for a point source charge B. Dipole field C. Sum of Coulomb's law fields D. Integral of Coulomb's law fields E. Gauss's law NOTE: In the configurations, x> and >. a. A uniform, horizontal circle (ring) radius R of charge. The test point is on the vertical line though the center of the circle, a distance yR above the center. c. A uniformly charged sphere of charge, radius R. The test point is on the vertical line though the center of the sphere at a distance r>R from the center. e. A horizontal line of charge length L and radius R<
