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

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

Results and Discussion As there were five similar experiments done‚ there is one common observed behavior – similar charges repel and opposite charges attract. The experiment went expected as there were no unusual observations recorded. In the first part‚ it was observed that when the plastic rod was rubbed it attracted the tissue bits. The explanation with this is‚ when the plastic rod was rubbed‚ it became electrically charged. Conduction happens when the tissue paper was rubbed into the plastic

ELECTRIC DISCHARGE MACHINING INTRODUCTION * Sometimes it is referred to as spark machining‚ * Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). * Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes‚ separated by a dielectric liquid and subject to an electric voltage. * One of the electrodes – ‘tool-electrode’ or ‘tool’ or ‘electrode’. * Other electrode - workpiece-electrode

the most due to the deaths caused by air pollution. Michael Graham Richard reports that 3.5 million deaths are caused by indoor air pollution and 3.3 million deaths are caused due to outdoor pollution. This essay will be discussing the use of electrostatic precipitator in reduction of air pollution. In total number of deaths are 6.8 million‚ this results are twice as many deaths as previously thought. According to BBC News in recent years‚ carbon dioxide emission have become a serious environmental

the science lab. In science‚ we would participate in a lab. One of my favorite labs was the owl pellet dissection. Owl pellets are owl throw up. In owl pellets you can find the bones of animals the owl consumed. In this lab we were to take out the bones we found in the pellet and construct the animal we found inside. Most people‚ like me‚ had a sort of rodent‚ but some people found birds in their pellet. Another one of my favorite things we did in science was the Sharpie tie dye lab in fifth grade

Physics Paper Otto Von Guericke‚ born November 20‚ 1601 in Madgeburg‚ Germany. He is one of the most famous scientists of all time. In 1650 he invented a “vacuum pump” it consisted of a piston and an air gun cylinder. Attached to the cylinder were two- way flaps that were designed to pull air out of whatever it would have been connected to. He used it to investigate the properties of the vacuum in a lot of his experiments. He also demonstrated the force of air pressure with extreme and dramatic
