1. There are one electron and one proton below with distance given in terms of r between each particle. Take r = B cm. Take charge of electron and proton in magnitude as 1.609 X 10 '19C and Coulomb constant k= 8.99 x109 Nmz/C2 a) Calculate net Electn'c eld at point P, what is the direction? (10 points) b) Calculate net Electric potential at P, does it have a direction? (10 points)
