when the u-235 nucleus absorbs a thermal neutron, ba-141 and kr-92 nuclei are produced along with some neutrons. how many neutrons are emitted?
Answers
A neutron is absorbed by the original uranium-235 nucleus before it splits into two new nuclei, krypton-92 and barium-141, which also releases three additional neutrons. These three neutrons can then split three more uranium-235 nuclei, releasing more neutrons with each fission, and so on.
When does a thermal neutron enter the U-235 nucleus?
A U-235 nucleus splits into two pieces when it takes in an extra neutron. Fission is the name of this process. Two to three neutrons are released each time a U-235 nucleus splits. Consequently, starting a chain reaction is a possibility.
U-235 atoms take in free neutrons during fission. Due to this, U-235 becomes unstable and fragments into two light atoms known as fission products.

The force of repulsion between two like-charged particles will increase if the distance between the charged particles is decreased.
What is coulomb's law?
According to Coulomb's law: The magnitude of each of the electric forces with which two point-at-rest charges interact is directly proportional to the product of the magnitude of both charges
And inversely proportional to the square of the distance that separates them and has the direction of the line that joins them.
The formula will be given as:
We can see that the force is inversely proportional to the distance of the two charges.
