f three charges are positioned as shown, what is the magnitude of the net force on Q2 ? Let Q1=−1.0×10−7C , Q2=3.6×10−9C , Q3=−1.6×10−10C , and d=4.0×10−3m . Three charges are placed in the x y plane. The x axis points horizontally to the right. The y axis points vertically upward. Charge Q subscript 1 is on the positive y axis at distance d from the origin. Charge Q subscript 3 is on the negative y axis at distance d from the origin. Charge Q subscript 2 is at the origin.

To calculate the magnitude of the net force on q2, use Coulomb's Law to calculate the individual forces between q2 and q1, and between q2 and q3, then add them vectorially.
Explanation:
To determine the magnitude of the net force on q2, we need to calculate the individual forces between q2 and q1, and between q2 and q3. The force between two charges is given by Coulomb's Law:
F= K(q1)(92)/12
where k is the electrostatic constant, ql and q2 are the charges, and r is the distance between them.
Applying this formula, we can calculate the individual forces and then add them vectorially to find the net force on q2.
