Answer to Question #181287 in Physics for Nicole

Question

Activity 2: Electric Potential Energy

1. Two-point charges Q1= 4.5 nC and Q2= 8.5 nC arr initially very far apart. They are then bought together, with a final spearation of 3.5 mm. How much work does it take to bring them together?

2. An electron is accelerated from rest through a potential difference of 15V. What is the changr ij electric potential energy of the electron?

3. In nuclear fission, a nucleus splits roughly in half.

  a) what is the potential 4.00 x 10^-14 m from a fragment that has 50 protons in it? (p=+ 1.602x10^-19 C)

  b) What is the potential energy of a similarly charged fragment at this distance?
