physics investigatory project class 11 on friction

Thales was incorrect in believing the attraction was due to a magneticĮffect, but later science would prove a link between magnetism and electricity. That friction rendered amber magnetic, in contrast to minerals such as magnetite, which Made a series of observations on static electricity around 600 BC, from which he believed People who had helped me directly or indirectly duringĪncient cultures around the Mediterranean knew that certain objects, such as rods ofĪmber, could be rubbed with cat's fur to attract light objects like feathers. Last but not the least I would like to thank all the Secondly I would also like to thank my parentsĪnd my friends who helped me a lot in finalizing this Research and I came to know about so many new Suspended in a vertical plane by making use ofĬoulomb9s law.= which also helped me in doing a lot of Of the two identical styro foam balls or pith balls The topic < To estimate the charge induced on each one Golden opportunity to do this wonderful project on I would like to express my special thanks of gratitude Many people have bestowed on me their blessings and In the accomplishment of this project successfully ĭepartment of physics Delhi Public School,Kalingaĭelhi Public School, Kalinga ACKNOWLEDGEMENT It is finalized under our guidance and supervision in the This report is the result of her endeavours and Styro foam balls or pith balls suspended in a vertical plane by Has successfully completed the physics investigatory projectĮntitled, To estimate the charge induced on each one of the two identical
