Electrostatics Electrostatics is a part of physics is that the study and analysis of electricity‚ its properties and its applications. Electrostatics was discovered when an ancient Greek philosopher named Thales. In 600 B.C.‚ Thales learned that when he rubbed amber with fur‚ it would start to attract other lightweight objects such as feathers and dust which is now known as a process called triboelectrification. This is also how we got the word electricity‚ which comes from the Greek word‚ elektron

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.

Capacitors and electrostatics PHY 114 Abstract: The purpose of this experiment was to measure the electrostatic force between two objects as a function of their signs and electrical charges. This was done using many equipment’s such as a glass and rubber rod. In addition‚ investigate how capacitors store energy electrostatically in an electric field‚ share charges and discharge. This was done by using equipment’s like voltage follower‚ DVM‚ powered breadboard unit and a selection of capacitors

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching

Lab: Electrostatic Coulomb Constant Rylee Rose Date: 1/28/13 Abstract: This experiment was done to study electrostatic and Coulomb’s law. Objective: The objective was to demonstrate the veracity of Coulomb’s Law. This was done by observing different equilibrium conditions of two pith balls that were equally charged. They were then constructed into a pendulum using strings. Calculations were done to determine the charge on pith balls‚ calculate the mass of the pith balls and to calculate

Electrostatics Lab Name: Bryan Michel Materials: Styrofoam cups Styrofoam plates PVC Pipe Fur Scotch Tape Procedures: You will be investigating charging object by friction. When you are asked to write your observations‚ please do so in a clear‚ complete manner. 1. Tape a piece of string to a Styrofoam cup and hang it from the edge of the desk so that it can move freely. Rub the outside of the cup with fur. Rub a PVC pipe with fur and bring it near the hanging cup.

CBSE TEST PAPER-01 CLASS - XII PHYSICS (Unit – Electrostatics) [ANSWERS] FV force between the charges in vaccuum = FM force between two charges in medium FV ⇒ Fm = k ⇒ if k increases‚ Fm decreases. Ans 01. Since K= Ans 02. Suppose rod P be negatively charged since it attracts rod R ⇒ R is positively charged since it repels rod Q ⇒ Q is negatively charged. So force between Q and R is attractive in nature. Ans 03. Since F = q E and a = F/m Since charge on proton
