And if two neutral objects are brought near each other, then obviously nothing at all will take place: since both objects are neutral, bringing them near each other introduces nothing new to the situation: we are simply bringing neutral atoms near some other neutral atoms! The electric force is a non-contact force. A charge may be positive or negative. Most of the time positive and negative charges are balanced in an object, which makes that object neutral. Use MathJax to format equations. . Because the repulsion energy is less than the nuclear energy .so , protons do not repel eachother. And being a force, the same laws and principles that describe any force describe the electrical force. Your prescription is not clear. 19.
