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/r
K = 9*10⁹

Z=50

e = 1.6*10^-19

r = 9*10^-15

so V = 8*10⁶ volts

V = 80*(10^-10)/(10^-15)

V = 80*[10^(-10-(-15))]

V = 80*10^5

so v =80*10^6
