6. (10 pts) In a research lab, a dust particle encounters a region where the electric field between two horizontal pieces of equipment can be modeled as a parallel-plate capacitor with a cross-sectional area of 1.50 cm2, a separation of 1.25 mm, and a charge of 35.0 mC (no typo here). a) Determine the electric field for this model. b)...

A hollow metal sphere has 5 cm and 9 cm inner and outer radii, respectively. The surface charge density on the inside surface is -150nC/m2. The surface charge density on the exterior surface is +150nC/m2 .Part AWhat is the strength of the electric field at point 4 cm from the center? Part B What is the direction of the electric field at...
Here's a cool example: Permanent magnets. If B are produced by currents, then what's up with permanent magnets? You don't have to plug them in, they just work. What's the current? One idea is that it could be the e' orbiting the nucleus. A charge moving in a circular loop is a sort of current. (You'll calculate this in Problem...
Two identical conducting small spheres are placed with their centers 0.270 m apart. One is given a charge of -12.0 nC and the other a charge of -18.0 nC. (a) Find the electric force exerted by one sphere on the other magnitude direction away from the other sphere (b) The spheres are connected by a conducting wire. Find the electric...
A honey bee of mass 135 mg has accumulated a static charge of +2.0 pC. The bee is returning to her hive by following the path shown in the figure. Because Earth has a naturally occurring electric field near ground level of around 100 V/m pointing vertically downward, the bee experiences an electric force as she flies. What is the...
Dispersion, absorption and refractive index: Describe in detail the physical model that allows you to understand how the refractive index depends on the ω frequency of the electromagnetic wave that passes through the dielectric material. explain succinctly, a) the dispersion phenomenon for ω >> ω0 and for ω << ω0 (you must derive the dispersion equation). (b) the absorption phenomenon....
How deep should be ocean to enhance physiologically harmful infrasonic waves of 6 Hz frequency? Take 1.47 km/s for the speed of sound in water and find the minimum and next to minimum depths of the ocean. The minimum depth, h1 = The next to minimum depth, h2 = What is the length of the string if the speed of...
