The nearest star that can go supernova is either Spica or IK Pegasi
Answer:
r=15.53 nm

Explanation:
Lets take electron is in between iron and uranium
Charge on electron
Charge on iron
Charge on uranium
We know that force between two charge

For equilibrium force between electron and iron should be force between electron and uranium
Lets take distance between electron and uranium is r so distance between electron and iron will be 37.5-r nm
Now by balancing the force

So r=15.53 nm
So force

helium group no val elect
mg is reactive when activated. when burned, very intense
