Magnitude and direction of Couloumb force.

In summary, the Coulomb force, also known as electrostatic force, is an attractive or repulsive force between two charged particles. Its magnitude can be calculated using Coulomb's law, which states that it is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The direction of Coulomb force depends on the type of charge on the particles, with like charges repelling and opposite charges attracting. Coulomb force is measured in newtons (N) in the SI system and dynes (dyn) in the cgs system. Additionally, Coulomb force is directly related to electric fields, with the electric field at a point being the force per unit charge experienced by a test charge placed at

Homework Statement


Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in the figure below.

a) 6.00 microcoloumbs
b)1.50 microcouloumbs
c)-2.00 microcouloumbs


Homework Equations



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



The Attempt at a Solution



a) 6*10^-6 * (1.50^-6)/(.03)^2 * 8.99^10^(-9) = 90, with direction to the right.
b) 1.50*10^(-6) * -2.00*10^(-6) * 8.99 * 10^(9) = -67.425 + 90 = 22.58, with direction towards the right.
c) The answer is just -67.425, towards the left.

Is this correctly done? If not, can anyone explain what I did wrong and tell me correct method please? Diagram below for reference.

FAQ: Magnitude and direction of Couloumb force.

1. What is the Coulomb force?

The Coulomb force, also known as electrostatic force, is an attractive or repulsive force between two charged particles. It is caused by the interaction of their electric fields.

2. How is the magnitude of Coulomb force calculated?

The magnitude of Coulomb force is calculated using Coulomb's law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

3. What is the direction of Coulomb force?

The direction of Coulomb force depends on the type of charge on the particles. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other.

4. What units are used to measure Coulomb force?

Coulomb force is measured in newtons (N) in the SI (International System of Units) system. In the cgs (centimeter-gram-second) system, it is measured in dynes (dyn).

5. How does Coulomb force relate to electric fields?

Coulomb force is directly related to electric fields. The electric field at a point is the force per unit charge experienced by a test charge placed at that point. Coulomb force is the force experienced by a charged particle placed in an electric field.
