two point charges are located on the y axis as follows :

Question

charge q1 = -1.50nc at y= -0.600m, and
charge q2 = +3.2nc at the origin (y=0)
what is the net force (magnitude and direction) exerted by these two charges on a third charge q3 = +5.00 nc located at y = -0.400 m

Answer 1

Answer 2

F = k Qa Qb /d^2
Like charges repel , unlike attract, so both pull down
so
F = k * (10*-9)^2 * 5 * ( -3.2/.4^2 - 1.5/ .2^2) Newtons
