Let's say you want to produce a (roughly) uniform electric field using a very large nonconducting sheet. However, you still want to be able to access the regions above and below the sheet, so a drill a small hole with a radius of 1.80 cm into the sheet. You can assume that very large means "infinite" in this context. The sheet has a surface charge density of 4.50 pC/m2. What is the magnitude of the electric field at a point 2.56 cm above the sheet after the hole is drilled into the sheet? You drill the hole such that the point we are considering lines directly above the center axis of the hole.

Hint: Remember that electric fields obey the superposition principle. What charge distribution can you add on top of the sheet to create the absence of charge (i.e., not net charge) in "hole" region?

Let's say we are planning on adding a very large modern sign to attract customers to our marijuana and tattoo shop that we run just north of Denver. We've completed a ton of market analysis and we are fairly confident that the sign will increase sales by $50,000 per year for the first two years, and then we think it will result in an increase of $35,000 per year for the next four years. The margins we earn on our...

Two large parallel copper plates are 3.60 cm apart and have a uniform electric field of magnitude E = 7.98 N/C between them (see the figure). An electron is released from the negative plate at the same time that a proton is released from the positive plate. Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other.

Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes. Of course, if you took an actual poll you would only get one number (your sample proportion, p-hat). But, imagine all the possible samples of 150 students that you could draw and the imagined histogram of all the sample proportions from those samples. 1. What shape would the histogram of all the possible sample proportions (p-hat's) have?...
