Instructions - Go to this simulation website: httpsa'iphet.colorado.eduienisimulationsicoulombs-law - Plavr with the values in this simulator to see how distance between point charges affects the strength of the electric force between them. Also. think about the DIRECTIONS of the force acting on each object and how the direction depends on the Law of Electric Charges {opposites attract; iikes repeh When you understand how this simuia tor works, answer the foiiowing assignment Questions: 1. Two identical metal spheres, each with a positive charge or, are separated bv a centretocentre distance r. What effect will each of the following changes have on the magnitude of the electric force F's-exerted on each sphere on the other: a] The distance between the two spheres is tripled b] The distance between the two spheres is halved. c} Both charges are doubled. d} One of the charges becomes negative. 2. Two small spheres of charge +5.0 pC and 4.0 mil are separated by a distance of 2.0 m. Determine the magnitude of the force that each ferce exerts on the ether. Describe the direction of these forces, relative to each ether. 3. Two identicallyr charged small spheres, of negligible mass, are separated by a centretecentre distance of 2.0 m. The force between them is 36 N. Calculate the charge on each sphere
