Final answer:
The work done by the electrostatic force on a charged particle as it moves from point B to point C can be calculated using the formula: W = q(V_C - V_B), where q is the charge of the particle and V_C and V_B are the potentials at points C and B respectively.
Step-by-step explanation:
The work done by the electrostatic force on a charged particle as it moves from point B to point C can be calculated using the formula: W = q(V_C - V_B), where q is the charge of the particle and V_C and V_B are the potentials at points C and B respectively.
In this formula, the work done is equal to the product of the charge and the difference in potentials between the two points.
For example, if the charge of the particle is 2.0 microcoulombs and the potential at point C is 5.0 volts while the potential at point B is 3.0 volts, the work done would be: W = 2.0 µC(5.0V - 3.0V) = 4.0 µJ.
