![]() In the Middle Ages, more material was found to act in a similar fashion and it was thought that electricity was some type of fluid for many centuries. The word for amber in Greek happens to be "electron" by the way. Thousands of years ago, people would rub a piece of amber with fur and watch with amazement as it attracted hair to it (similar to a favorite trick of many Baby Boomers in their childhoods when they would stick their arm near the television screen and watch their arm hairs stick up straight). (Remember: The force unit of Newton, N = kg m s–2) Show transcribed image textġ NAME: Lab Section: Score: Cathode Ray Tube Experiment Background Electric fields and electricity were a mystifying wonder to humans ever since ancient times up until the latter half of the 19th century. Particles (in kg C–1) given a deflection length of 5.00 cm and a Used in Problem #2 and the velocity solved for, use Equation 1 toĬalculate the mass to charge ratio (m/q) of the cathode ray Given the same electric field strength and electric displacement Strength in another experiment is 1.8 x 104 N C–1.įrom these parameters, both the magnetic displacement and theĮlectric displacement were each measured to be 6.0 cm. The Newton (N = kg m s–2) and the unit of current is the Ampere (A Per Amp meter (or 5.0 x 10–4 N A–1m–1), where the unit of force is ![]() The magnetic field strength in an experiment is 5.0 x 10–4 Newtons Particles based on this observation of the deflection of theĬathode ray passing between the two plates? Thomson conclude about the nature of the cathode ray
