A fancy lecture demo designed to gauge electric fields

Reference no: EM13679838

A fancy lecture demo designed to gauge electric fields is shown in the figure above. A pith ball of mass 0.510 g and positive charge q = 42.6x10-6 C is suspended on a string of negligible mass in a uniform electric field. We observe that the ball hangs at an angle of Theta=15.0 from the vertical. What is the magnitude of the electric field?

What direction does the wave travel and what is its speed : A sinusoidal wave in a string is explained by the wave function y = (0.06m) sin (4.4x - 7.0t) where x and y are in meters and t is in seconds. (a) In what direction does the wave travel and what is its speed? (

Compute the time for the ice to completely melt : An ice chest is constructed of a 0.4 mm thick plain-carbon steel plate, a 1.9 cm thick layer of Styrofoam {k=0.033 W/(m-C)} and a 0.65 cm thick fiber glass liner. The cooler has inside dimensions of 25x40x100 cm. The

Two oppositely charged-isolated parallel plates : Which statements are true for two oppositely charged, isolated parallel plates: C=capacitance, U=stored energy (Q and -Q = charge on the plates). Note: Isolated plates cannot lose their charge. True or False: Inserting a dielectric decreases U.

What mechanism do quantum effects become observable : By what mechanism do quantum effects become observable in normal life at the macroscopic level? For instance, when two molecules "collide" is the momentum a probabilistic event wherein the end state is not unique? Another example, through a chemical ..

Rear view mirror on a car is convex with radius of curvature : Presume the rear view mirror on a car is convex with a radius of curvature of 21 m. How does your answer change when the motorcycle is 14 m behind the car? If a motorcycle is 49 m behind the car, what is the magnification of the motorcycle?

What is in the space between circling gnats and the fly : There is a common analogy about the structure of an atom, such as the nucleus is a fly in the centre of a sports stadium and the electrons are tiny gnats circling the stadium (tip of the hat to 'The Greatest Show on Earth') however what is in the spa..
