Two large parallel plates X and Y are placed a distance of 5.0 mm apart and connected to the terminals of a 200 V d.c. supply, as shown. [Figure 29.1] A small oil drop at P carries one excess electron. What is the magnitude of the electrostatic force acting on the oil drop due to the electric field between the plates?
