A positive and a negative charge, each of magnitude 1.7 10-5 C, are separated by a distance of 11 cm. Find the force on each of the particles.
what formula do i use?
Use Coulomb's law.
F = k Q1 Q2/R^2
Each charge will experiences an attraction force F towards the other. The magnitude of the forces will be equal.
R = 0.11 meter
Q1 = Q2 = 1.7*10^-5 Coulombs
k = 8.99*10^9 N/m^2 C^2

To calculate the force between two charges, you can use Coulomb's Law. Coulomb's Law states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. The formula for Coulomb's Law is:
F = k * (q1 * q2) / r^2
where:
F is the force between the charges,
k is the electrostatic constant (k = 9.0 * 10^9 Nm^2/C^2),
q1 and q2 are the magnitudes of the charges, and
r is the distance between the charges.
In this case, the magnitude of both charges is 1.7 * 10^-5 C, and the distance between them is 11 cm. However, it's important to note that distance should be in meters, so we need to convert 11 cm to meters:
11 cm = 0.11 m
Now we can plug in the values into the formula:
F = (9.0 * 10^9 Nm^2/C^2) * ((1.7 * 10^-5 C) * (1.7 * 10^-5 C)) / (0.11 m)^2
Now you can calculate the force using a calculator.
