A uniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance 5.4 cm. A proton is released from rest at the surface of the positively charged plate. The value of the constant electric field between the plates is 166.8 N/C.

Use:

Mass of a proton= 1.67 × 10-27 kilograms

Charge of a proton = 1.60 × 10-19 C

k = 9 x 109 Nm2 / C2

ε0 = 8.85×10−12 F⋅m−1

1. Calculate the value of the acceleration of the proton then enter the letter corresponding to the correct answer in the box (this entry requires exact match. please enter the letter in lower case and do not enter any spaces, commas or dotts).

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
