2. At the point of fission, a nucleus of
235U that has 92 protons is divided into two smaller
spheres, each of which has 46 protons and a
radius of 5.9 10^-15 m.
What is the magnitude of the repulsive force pushing these two spheres apart?
The value of the Coulomb constant is
8.98755 10^9N m2/C2
1. 4.12586 10^-11 N m
2. Unable to determine
3. None of these
4. 4.02599 10^34 N m/C
5. 4.75067 10^20 N/C
6. 3496.5 N
