While undergoing fission, a uranium-235 nucleus with its 92 protons splits into two smaller nuclei each of which contains 46 protons and has a radius of 5.90 x 10^-15m. What is the magnitude of the repulsive force between the two nuclei just after the split?

Answer 1

Use Coulomb's law.

The charge of each nucleus is Q = -46e and the separation is twice the radius.

F = k Q^2/d^2

Answer 2

thankyou :)
