F = Qq/4πεr^2

q , Q - two charges

r - distances between charges

1/4πε - the constant of equation which is 9 x 10^9

F = (2 x 10^-4)(8 x 10^-4)(9 x 10^9)/((0.3)^2)

= 16 000 N

How is the electric field between two charges calculated?

The electric field between two charges is calculated using Coulomb's law, which states that the electric field strength (E) is equal to the force (F) between the charges divided by the charge (q) experiencing the force. The formula is E F/q.


How do you calculate the electric force between two charges?

The electric force between two charges can be calculated using Coulomb's law, which states that the force is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them. The formula is: F = k * (q1 * q2) / r^2, where F is the electric force, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.


When will be the force between two similar charges maximum?

The force between two similar charges will be maximum when the charges are closest to each other, as the force between charges follows an inverse square law relationship with distance.


If one of two interacting charges is doubled the force between the charges will .?

The force between the charges will increase by a factor of 2, following Coulomb's Law, which 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.


Why electrostatic force between two charges is called central force?

The electrostatic force between two charges is called a central force because it acts along the line joining the two charges, targeting the center of the system formed by the charges. This means that the force is radial in nature, pointing towards or away from the central point between the charges.

Suppose there are two charges charge A and charge B. What determines the magnitude of the force between the two charges?

The magnitude of the force between two charges is determined by the product of the magnitudes of the charges and inversely proportional to the square of the distance between them, as described by Coulomb's law. The force is greater with larger charges and decreases as the distance between the charges increases.


How does the distance between 2 charges impact the force between them?

The force between two charges is inversely proportional to the square of the distance between them. This means that as the distance between the charges decreases, the force between them increases, and vice versa.


How does static electricity move objecs?

The electric lines of force. A repelling force is between two like charges. An attractive force is between two opposite charges.


What two factors determine the amount of electric force between two objects?

The amount of electric force between two objects is determined by the magnitude of the charges on the objects and the distance between them. The force increases with the magnitude of the charges and decreases with the square of the distance separating the objects.


What is the magnitude force of 2 opposite charges?

The magnitude force between two opposite charges can be calculated using Coulomb's law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, the force is given by F = k * |q1 * q2| / r^2, where q1 and q2 are the magnitudes of the charges, r is the distance between them, and k is the electrostatic constant.


How does the electric force change between two positive charges when the distance between the charges is tripled?

The electric force between two positive charges will decrease by a factor of 9 (inverse square law) when the distance between the charges is tripled.
