Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus. Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes.

Explanation:
The resistance of the cylindrical wire is 
.
Here 
is the resistance, 
is the length of the wire and 
is the area of cross section. Since the wire is cylindrical 
. Rearranging the above equation,
Here 
.
Substituting numerical values,
The length of the wire is 
An electron is negatively charged.
