Question

Answers must be expressed in engineering notation (when the exponent of the base 10 multiplier is not a multiple of 3, press ENG or SHIFT+ENG, whichever the case.)
Example: 0.06N or 6.0x10-2 N must be expressed to 60x10-3 N or 60mN

At a corner of a 30 mm x 40 mm rectangle is placed a charge of
-40µC and at the two adjacent corners are charges of +20µC, as
shown in the figure. Determine:
a. The potential at the 4th corner P.
b. The potential at the center of the rectangle.
c. The work that must be done by an external force to bring a
charge q, = +5µC from the center of the rectangle to the 4th
corner P.
91 = +20 µC
92 = -40 µC
B
30 mm
40 mm
93 = +20 µC
