The charges and coordinates of two charged particles held fixed in the xy plane are: q1=6.00 ?C, x1=6.700 cm, y1=4.600 cm, and q2=8.90 ?C, x2=1.039 cm, y2=11.467 cm,
Find the a) magnitude and
b) direction of the electrostatic force on q2?
What are the c) x and
d) y coordinates of a third charge q3=8.60 ?C, if the net electrostatic force on q2 is zero?
