Question

How does electric force depend on the amount of charge and the distance between charges

Answer 1

F = k×
`(q1q2)/(r2)`

Step-by-step explanation:

• The attractive or repulsive forces which act between any two charged species is an electric force.
• The electric force depends on the distance between the charged species and the amount of charge which can be calculated by the formula given as follows

F = k×
`(q1q2)/(r2)`

where, K is coulombs constant, which is equal to - 9 x10^9
`Nm^2/C^2.`

• The unit for K is newtons square meters per square coulombs.
• This is known as Coulomb's Law.
