The formula for calculating electrostatic work is W = q1 * q2 * k, where q1 and q2 are the magnitudes of the two charges involved and k is the Coulomb constant.
The magnitude of the two charges involved can be determined by measuring the strength of the electric field or by using a voltmeter to measure the potential difference between the two charges.
The Coulomb constant, denoted by k, is a proportionality constant that relates the magnitude of electric charge to the strength of the electric force. Its value is approximately 8.99 x 10^9 N * m^2 / C^2.
Yes, you can calculate electrostatic work for multiple charges by summing the individual work values for each pair of charges. This is known as the principle of superposition.
Electrostatic work is related to potential energy through the equation W = -ΔPE, where W is the work done, ΔPE is the change in potential energy, and the negative sign indicates that work is done by the system when potential energy decreases.
