Answer:
a, V = 65.6V
b. V = 131.0V
C. V = 131.0V
Explanation:
Given
Total electric charge distributed uniform at surface of metal sphere where radius is R = 24cm
R = 24cm = 0.024m
we have to find potential at different distance
a. r = 48cm = 0.048m
b. r = 24cm = 0.024m
c. r = 12cm = 0.012m
a. <u>solution</u>
Here the distance r is grater then R,we can get the potential outside of sphere
now we plug the value <em>q</em> and <em>r</em> in potential<em> v</em>
=65.6V
b.<u>solution</u>
Here distane r is the same from radius R, so we can get potential inside sphere
Now we plug the value of R and q
3.<u>solution</u>
Inside sphere electric feild is zero.so potential is the same every point inside sphere and equal potential on the surface
