Question

What is the electric potential at the surface of a gold nucleus? The radius is 6.6×10-15
m and the atomic number Z=79

Answer 1

Answer:

The electric potential at the surface of the gold nucleus is given as

V=

4πε

0

r

Ze

By substituting the values in the above equation we get

V=

6.6×10

−5

9×10

9

×79×1.6×10

−19

V=172.3×10

−5

Hence, the electric potential is 172.3×10

−5
