P2-1 A +2nC point charge is located in between a +5nC charged flat plate of area 1.2m2 and 
another point charge of -3nC. The latter is located 6mm to the right of the first (+2nC) point 
charge, along a line that intersects the plate at 90o. The plate is located 4.3mm from the first, 
(+2nC) charge. 
A) What is the total electric force exerted on the +2nC charge? 
B) What is the total electric force exerted on the -3nC charge? 
C) What is the total electric field "seen" by the +2nC charge, as generated by the -3nC and 
+5nC objects? 
E) What is the electric field generated by flat plate (magnitude and direction), a distance 
0.5mm away from it? 
F) What is the total electric field (magnitude and direction) generated by all three charges, at 
a location 2mm to the right of the -3nC charge?
