Two point charges are fixed on the y axis: a negative point charge q1 = -34 μC at y1 = +0.19 m and a positive point charge q2 at y2 = +0.32 m. A third point charge q = +8.9 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 23 N and points in the +y direction. Determine the magnitude ofq2.

To determine the magnitude of q2, we can use Coulomb's Law, which states that the magnitude of the electrostatic force between two point charges is given by:

F = k * |q1 * q2| / r^2

Where:
- F is the magnitude of the electrostatic force
- k is the electrostatic constant (9 x 10^9 N*m^2/C^2)
- q1 and q2 are the magnitudes of the charges
- r is the distance between the charges

1. First, let's determine the distance between q1 and q. Since they are located on the y-axis, the distance between them is the absolute difference in their y-coordinates:

r1 = |y1 - 0|

Substituting the given values, we have:

r1 = |0.19 m - 0|
r1 = 0.19 m

2. Next, let's determine the distance between q2 and q. Similarly, since they are located on the y-axis, the distance between them is the absolute difference in their y-coordinates:

r2 = |y2 - 0|

Substituting the given values, we have:

r2 = |0.32 m - 0|
r2 = 0.32 m

3. Now, let's find the magnitude of q2. We can rearrange Coulomb's Law to solve for q2:

|q2| = (F * r^2) / (k * |q1|)

Substituting the given values, we have:

|q2| = (23 N * (0.32 m)^2) / (9 x 10^9 N*m^2/C^2 * |(-34 μC)|)

|q2| = (23 N * 0.1024 m^2) / (9 x 10^9 N*m^2/C^2 * 34 x 10^-6 C)

|q2| = 0.2357 C

Since |q2| is the magnitude of q2, the magnitude of q2 is 0.2357 C.

Oh! From your "school subject", I thought maybe you need help wiping your nose or tying your shoes. Is this physics?
