Can you please assist in explaining and solving the following problems:

A piece of purple plastic is charged with 7.67 X 106 extra electrons compared to its neutral state. What is its net electric charge (including its sign) in coulombs? A glittering glass globe is given a net electric charge of 2.65 X 10'6 C. Does the globe now have more or fewer electrons than it does in its neutral state? How many more or fewer? Two particles, one with charge 3.77 x 10'6 C and the other with charge 6.07 x 10'6 C, are 0.0659 m apart. What is the magnitude of the force that one particle exerts on the other? Two new particles with identical positive charge q3 are placed the same 0.0659 m apart. The force between them is measured to be the same as that between the original particles. What is 13 ? :IC 43 Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight. Assuming equal point charges (only an approximation), calculate the magnitude of the charge if electrostatic force is great enough to support the weight of a 12.0 mg piece of tape held 1.00 cm above another. Question Credit: OpenStax College Physics An electron and a proton are fixed at a separation distance of 873 nm. Find the magnitude E and the direction of the electric field at their midpoint. The direction E = N/C O is toward the proton. O is toward the electron. O cannot be determined. O is perpendicular to the line of the particles.An electron is located on the x-axis at xo = -8.55 x 10 m. Find the magnitude and direction of the electric field at x = 4.87 x 10 m on the x-axis due to this electron. magnitude: N/C direction: O neither of these O positive x-direction O negative x-direction
