The acceptable units for the electrostatic force are N (newtons) and C (coulombs).
To determine which units are acceptable for the electrostatic force, we need to understand what units are commonly used for measuring force and specifically for measuring electrostatic force.
The SI unit for force is the Newton (N). The electrostatic force is a type of force that occurs between charged objects and is measured in Newtons (N). So, N is an acceptable unit for the electrostatic force.
Let's analyze each of the given units:
- W (Watts): The watt is the SI unit for power, not force. It is not an acceptable unit for the electrostatic force.
- lb (pound): The pound is an imperial unit for weight, not force. It is not an acceptable unit for the electrostatic force.
- oz (ounce): The ounce is also an imperial unit for weight, not force. It is not an acceptable unit for the electrostatic force.
- Ω (Ohm): The Ohm is the SI unit for electrical resistance, not force. It is not an acceptable unit for the electrostatic force.
- C (Coulomb): The Coulomb is the SI unit for electric charge, not force. It is not an acceptable unit for the electrostatic force.
- V (Volts): The Volt is the SI unit for electric potential, not force. It is not an acceptable unit for the electrostatic force.
- A (Ampere): The Ampere is the SI unit for electric current, not force. It is not an acceptable unit for the electrostatic force.
- N (Newton): The Newton is the SI unit for force and is acceptable for the electrostatic force.
- kW·h (kilowatt·hour): The kilowatt-hour is a unit for energy, not force. It is not an acceptable unit for the electrostatic force.
- tons: The ton is an imperial unit for weight, not force. It is not an acceptable unit for the electrostatic force.
Therefore, the only acceptable unit for the electrostatic force from the given options is N (Newton).
