problem 2 80 hc point charge is fixed at the origin of the 4s 780 hc point charge of mass 50 gru

Step 1: Calculate the total energy of the -7.80 C charge when it is at 0.800 m.

Question

Problem 2: An 80 C point charge is fixed at the origin. Another 7.80 C point charge with a mass of 50 grams is moving towards the charge at the origin. It has a speed of 0.22 m/s when it is at a distance of 0.800 m. Calculate: (a) The total energy of the -7.80 C charge when it is at 0.800 m. (b) The position along the axis where the speed of the -7.80 C charge is zero, which is 0.32 m. Problem Two: Infinite parallel planes are separated by 0.22 cm. The planes have equal and opposite charge densities. The charge density of the positive plane is 9 MC/m^2. Calculate: (a) The magnitude of the electric field between the planes. (b) The potential difference from the positive plane to the negative plane. (c) The potential along the equipotential surface at a distance of 10 cm from the positive plate. Let the potential along the positive plane equal 3.0 kV.
