Which factors affect the electrical force between two objects?

mass and distance between them

charge and distance between them

mass and electric field strength

charge and mass

The factors affecting the electrical forces between 2 objects are the charge and the distance between them because we calculate the electric force between them by coloumb's law which equals = K*Q1 * Q2/r^2

Where,

Q1 and Q2 are the charges of 2 objects and they are directly proportional to the electric charge so, by increasing them the electric charge increases

K is the coloumb's constant and approximatly equals 9*10^9 N. m^2/c^2

r is the distance between the 2 objects and it is inversly proportional to the electric charge so, by increasing distance the electric charge decreases
