The electron gun in a television tube accelerates electrons (mass = 9.11  10-31 kg, charge = 1.60  10-19 C) from rest to 3.00  107 m/s within a distance of 2.00 cm. What electric field is required?

Question 2

At the point of fission, a nucleus of U-238, with 92 protons is divided into two smaller spheres each with 46 protons and a radius of 5.9  10-15 m. What is the repulsive force pushing the two spheres apart when they are just touching one another? (The mass of the U-238 nucleus is 3.98  10-25 kg.)
