Question

1) If the potential due to a point charge is 8.00×10³V at a distance of 12.0 m, what are the sign and magnitude of the charge?

2) There are two charges q₁ = 35 μC and q₂ = -50 μC fixed in place on the x-axis. q₁ is located at x=0 and q₂ is located at x=0.5 What is the location on the x-axis where the potential equals 0?

3) In nuclear fission, a nucleus splits roughly in half. (a) Ignoring the effect of electrons, what is the potential 5.50×10^-14m from a fragment that has 46 protons in it? (b) What is the potential energy in MeV of a similarly charged fragment at this distance?

4) To form a hydrogen atom, a proton is fixed at a point and an electron is brought from far away to a distance of 0.529×10^-10m, the average distance between proton and electron in a hydrogen atom. How much work is done?
