How would I know when the charges are negitive and positive? Along the x and y-axis Thanks in advance for your help.
Coulomb's law is a fundamental law in physics that describes the relationship between electric charges and the resulting force between them. It states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The mathematical expression of Coulomb's law is F = k(q1q2)/r2, where F is the force, k is the Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.
Vectors are used in Coulomb's law to represent the direction and magnitude of the electric force between two charges. The direction of the force is determined by the direction of the electric field, which is a vector quantity.
The electric field can be calculated by dividing the electric force by the magnitude of the test charge. Mathematically, it is expressed as E = F/q0, where E is the electric field, F is the electric force, and q0 is the magnitude of the test charge.
Coulomb's law with vectors is used to understand and predict the behavior of electric charges in various systems, such as electronic circuits, particle accelerators, and even the behavior of atoms and molecules. It is also essential in designing and optimizing technologies such as batteries, capacitors, and electric motors.
