As shown in the figure, two insulating spheres, having
diameters 45.0 cmcm , and carrying a uniform positive
and negative charges with magnitude 180 μCμC ,
are 1.00 mm distance apart center to
center
A) What will the voltmeter read, if it is is connected to the
points (nearest points) a and b
on their surfaces?
B)Is a or b point at the higher
potential?
C)
How can you know this without any calculations?
