To calculate the electrical cost utilizing electrostatics, we have to contemplate the power between two charged particles. The power could be calculated utilizing Coulomb’s Legislation:

F = ok * (q1 * q2) / r^2

the place F is the power, ok is Coulomb’s fixed, q1 and q2 are the fees, and r is the space between the fees. As soon as now we have the power, we will use the equation of movement to calculate the cost.
For instance, if the power is 0.1 N, Coulomb’s fixed is 8.99 * 10^9 N m^2 C^-2, and distance is 1 meter, we will calculate the cost as follows:

F = ok * (q1 * q2) / r^2

Rearranging the equation to resolve for cost, we get:

q1 * q2 = F * r^2 / ok

Assuming q2 is 2 C and r is 1 meter, we will calculate the cost q1 as follows:

q1 = (0.1 N * 1^2) / (8.99 * 10^9 N m^2 C^-2) = 0.000000011 C
