STATEMENT According to Coulomb’s law: The electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of charges. The electrostatic force of attraction or repulsion between two point charges is inversely proportional to the square of distance between them. MATHEMATICAL REPRESENTATION OF COULOMB’S LAW Consider two point charges q1 and q2 placed at a distance of r from each other. Let the electrostatic force between them is F. According

Riley Jefferson Block 7/8 October 8th 2012 Electrostatic Gedanken Lab Group Gamma Objective: The objective of this lab is to determine the charge on a pith ball. Hypothesis: I fully believe that the charge of the pith ball will be positive. The formula I will use to prove this is Coulomb’s Law‚ (Fe=(k*q1*q2) / r²). ‘Fe’ is equal to the electrostatic force between the spheres‚ measured in Newton’s. It is also a vector quantity‚ and it’s in absolute value. Secondly‚ ‘k’ is equal to Coulomb’s

Franklin bell experiment Report Introduction After much thought as to what experiment to do‚ I decided to do an electrostatic experiment using the Franklin bell. I had to try and find different energy sources that would work for me. Any electronic instrument would give off enough electricity‚ but I eventually settled on using a electric bug zapper because it was easy to set up the crocodile clips with it. Afterwards I tried the same experiment with a television set‚ using tinfoil which gave static

One World Electrostatic Precipitators Electrostatic precipitators are machines designed to reduce pollution in industrial applications. Typically fitted to the stacks of factories and power stations‚ electrostatic precipitators are designed to filter out dust particles from exhaust gases produced by industrial work. 99.9% of the dust particulates is captured by the precipitator‚ reducing the amount of dirty air passing into the atmosphere.

Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons‚ electrons and neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra
