How can electric forces be measured?
A torsion balance, which is an extremely sensitive tool for measuring extremely weak forces, can be used to measure electric forces or any other kind of force.

Electric forces can be measured using a device called an electrostatic force sensor, which quantifies the force between charged objects. Additionally, Coulomb's law can be applied for mathematical calculation of electric forces based on charge and distance.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
