The energy released during a nuclear reaction is a result of

the conversion of matter into energy

Explanation:

A nuclear reaction is a reaction in which there is a change in the nuclei of the atoms involved. The two most important examples of nuclear reactions are:

- Nuclear fission: it occurs when a heavy, unstable nucleus breaks apart into two or more lighter nuclei

- Nuclear fusion: it occurs when two lighter nuclei fuse together into a heavier nucleus

In both cases, the total mass of the final products is smaller than the total mass of the initial nuclei: this means that part of the mass of the initial nuclei has been converted into energy, according to Einstein's formula:

where is the variation of mass and c is the speed of light. Since the value of c is very large, we can see from the formula that even a small amount of is able to produce a huge amount of energy, and this is a typical feature of any nuclear reaction.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
