A positive and a negative charge are positioned as shown:

+
| 3.00 meters
- _______|
4.00 meters

Q1 = 4.00 microCoulomb
Q2 = -4.00 microCoulomb

1. What is the distance between the charges?
2. What is the angle of West of south?
3. What is the force of + on -?
4. What is the force of - on +?

To calculate the distance between the charges, you can use the Pythagorean theorem. The distance is equal to the square root of the sum of the squares of the horizontal and vertical distances.

Horizontal distance = 3.00 meters
Vertical distance = 4.00 meters

Distance = √(3.00^2 + 4.00^2)
Distance = √(9.00 + 16.00)
Distance = √25.00
Distance = 5.00 meters

Therefore, the distance between the charges is 5.00 meters.

To calculate the angle of West of South, you can use trigonometry.

Angle = arctan(vertical distance / horizontal distance)

Angle = arctan(4.00 / 3.00)
Angle ≈ 53.13 degrees

Therefore, the angle of West of South is approximately 53.13 degrees.

To calculate the force of the positive charge (+) on the negative charge (-), you can use Coulomb's Law.

Force = (k * |Q1 * Q2|) / (distance^2)

where:
k = Coulomb's constant (8.99 x 10^9 Nm^2/C^2)
Q1 = magnitude of charge 1 (4.00 microCoulomb = 4.00 x 10^-6 C)
Q2 = magnitude of charge 2 (-4.00 microCoulomb = -4.00 x 10^-6 C)
distance = distance between the charges (5.00 meters)

Force = (8.99 x 10^9 * |4.00 x 10^-6 * -4.00 x 10^-6|) / (5.00^2)
Force = (8.99 x 10^9 * 16.00 x 10^-12) / 25.00
Force = 5.752 x 10^-3 N

Therefore, the force of the positive charge on the negative charge is approximately 5.752 x 10^-3 N.

Similarly, to calculate the force of the negative charge (-) on the positive charge (+), you can use the same formula and the same magnitudes of charges, but this time the distance is the same.

Force = (8.99 x 10^9 * |4.00 x 10^-6 * -4.00 x 10^-6|) / (5.00^2)
Force = (8.99 x 10^9 * 16.00 x 10^-12) / 25.00
Force = 5.752 x 10^-3 N

Therefore, the force of the negative charge on the positive charge is approximately 5.752 x 10^-3 N.
