Problem 5: UP 7.43
The electric field in a region is pointed away
from the z-axis and the magnitude depends on
the distances from the axis. The magnitude of
the electric field is given as E = a/s where a is
a constant. Find the potential difference
between the two points P₁ and P2, shown in the
figure to the right. Explicitly state the path over which you conduct the integration for the line
integral.
