Final answer:
The potential difference (PD) between the plates is 100,000V or 100kV.
Step-by-step explanation:
The potential difference (PD) between the plates can be found using the equation:
PD = Force / Charge
Given that the force experienced by the charge is 10-5N and the charge is 10-10C, we can substitute these values into the equation to find the PD:
PD = (10^-5N) / (10^-10C) = 10^5V = 100,000V
Therefore, the potential difference between the plates is 100,000V or 100kV. The correct option is b) 100V.
