What is Electrostatic Force Microscopy? Electrostatic Force Microscopy (EFM) is a scanning probe microscopy technique that measures the electrostatic interactions between a conductive probe and a ...

Magnetic force can overcome gravity. That’s why this magnet can hover in mid-air. Electrostatic force also attracts and repels objects. Rubbing the balloon on another surface creates a small ...

If you’ve ever felt your hair lift as you take off a synthetic-fibre jumper, you will be familiar with the phenomenon of electrostatic force. Coulomb’s Law in action, the force resulting from ...

They are both charged with charge q and both have mass m. They dangle under the influence of both electrostatic forces and gravitational force. If both strings are the same length then the ...
