Components of a vector,
Direction (measured from x-axis),
q should repel the 1.0 nC charge. Force F12 is along the y-axis in the negative direction.
The sum of the y-components of the force due to the two 2.0 nC charges should have the same magnitude as the force due to q.
The magnitude of r is the same for the two 2.0 nC charges,
r = 3.0 cm i + 2.0 cm j = 0.03 m i + 0.02 m j
r = 0.0361 m
The net force on the 1.0 nC in the figure charge is zero. What is q?
