PPT-ELECTROSTATICS Properties of electric charges

Charges are conserved Charges are additive in nature Charges are quantised PROPERTIES OF ELECTRIC CHARGES PRODUCTION OF ELECTRIC CHARGE We can get electric charge by three ways By friction or rubbing. In an equilibrium situation there cannot be an electric field inside a conductor as this would cause charges electrons or ions to move around Charge density inside a conductor is zero This follows from Gausss law As the charge density This does no Conductors. Prof. Hugo . Beauchemin. 1. Introduction. We have seen most of the powerful concepts needed to understand electrostatics. W. e now turn to concrete applications, solving the equations. we saw for various types of system encountered in experiments . Units of Chapter 16.

The fundamental rule at the base of all electrical phenomena is that . like charges repel and opposite charges attract. An object that has unequal numbers of electrons and protons is . What is Electrostatics?. The study of stationary electric charges and electric fields. . - all ordinary matter contains both positive and negative charges.. . - most matter is electrically neutral because it. Coulomb's Law : . Coulomb's Law states that the force between two point charges Q. 1. and Q. 2. is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.. charged and how does . a charged object . affect other objects . in its vicinity?.
