Determine the distance of separation required for two 1.00 µC charges to be positioned so that the repulsive force between them is equivalent to the weight (on Earth) of a 1.00 kg mass. A Consider an electron and a proton separated by a distance of 1.0 nm. (a) Calculate the magnitude of the gravitational force between them. (b) Calculate the magnitude of the electric force between them. (c) Explain how the ratio of these gravitational and electric forces would change if the distance were increased to 1.0 m. Particles of charge q and 3q are placed on the x-axis at x = -40 and x = 50, respectively. A third particle of charge q is placed on the x-axis,and the total electric force on this particle is zero.Determine the position of the particle.
