If two metal balls each have a charge of -10^-6 c and the repulsive force between them is 1 n, how far apart are they? (coulomb's constant is k = 9.0x 10^9 n-m^2/c^2? 9.5 m 9.0 mm 9.5 cm 0.9 m .

The distance between the charges is 9.5 cm

(c) is correct option

Explanation:

Given that,

Charge

Force F = 1 N

We need to calculate the distance between the charges

Using Coulomb's formula

Where, q = charge

r = distance

F = force

Put the value into the formula

Hence, The distance between the charges is 9.5 cm

explanation:

the masses of the objects and the distance between them

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
