`        Electric potential at the surface of an atomic nucleus z=50 of radius 9×10^-15 `
one year ago

```							Note that in a nucleus there are only one entity that contains charge i.e proton. Neutron also resides in nucleus but it is neutral. since Z = atomic number = number of protons each having electronic charge e = 1.6*10^-19C  V = (k)*(Q)/R ------------------[ potential at the surface of nucleus] V = (k)*(Z*e)/R ------------------[ Total charge = (number of protons)*e ] k = 9*10^9Nm^2/C^2 , Z = 50 , e = 1.6*10^-19C , r = 9*10^-15m V = (9*10^9*(50)*(1.6)*10^-19)/(9*10^-15) V = (9*50*1.6*10^9-19)/(9*10^-15) V = 9*80*10^-10/9*10^-15 V = 80*(10^-10)/(10^-15) V = 80*[10^(-10-(-15))] V = 80*10^5 so V = 8*10^6 volts

```							V= KQ/r = KZe/rK = 9*109Z=50e = 1.6*10-19r = 9*10-15so V = 8*106 volts….............................................................
