Using the given charge-to-mass ratios for electrons and protons, and knowing the magnitudes of their charges are equal, what is the ratio of the proton's mass to the electron's? (Note that since the charge-to-mass ratios are given to only three-digit accuracy, your answer may differ from the accepted ratio in the fourth digit.)
Why can't we really draw a true representation of an electric field? Can there be an electric field at a point where there is no charge? Can there be a charge at a place where there is no field? Please write a one or two-sentence answer to each of these questions.
What is the magnitude of the electric field at a point midway between a -5.9 uC and a +8.2 uC charge 8.8 cm apart? Assume no other charges are nearby. Express your answer using two significant figures: E= (what value) in (what units)? What is the direction of the electric field? Toward the positive charge Toward the negative charge P.S. I know nothing about this but I have a good idea are some quick google help. I feel like I understand the concept but I want to verify the work before I'm able to help a friend with this problem. It would be helpful if you can list all the steps- I can reverse engineer with no issues.
What is the approximate electrostatic force between two protons separated by a distance of 1.0 x 10^-5 meter? Is it attractiv4 or repulsive? Show your solution.
Use GFSA (Given, Find, Solution, and Answer) on the given space below. Encircle your final answer, write it in scientific notation with 2 decimal places (if possible). An cylinder with radius 1 m and length 1.5 m has an infinite line of charge with a linear charge density of 30 C/m. ( please Make an illustration of the problem) (c) Calculate the electric field at a point 3 m away from the infinite line of charge.
Find the electric field of an infinite, flat sheet with charge distribution σ = 17.7 ×10^−12C/m2 by integrating the field produced and by using Gauss’s law. Now thatyou found the electric field of this sheet, we produce a hole of radius 15 m on thesheet and we ask you to find the electric field of this new sheet 52.7 m away fromthe infinite sheet on the central axis of the hole. Mind helping me out please, I got a few steps in but not sure where to go so I'm convinced I'm doing it wrong. I asked some peers and they said the answer was 0.96. Thanks
State what is meant by electric field strength at a point in space. How is its direction defined? Given that the magnitude field strength, E, at a distance r from a point charge Q is given by the formula: ?= 2/4??0 ?/?2 calculate the magnitude of the electric field at a point which is 10 cm from a positive 24 μC charge. Use ?=2/4??0 = 9×109 m/f. Give your anser in v/m.
I am having a hard time understanding why the solved answer on your site, for the following question, uses x-2 instead of x+2 for the -2q charge. I attached my work for part A as well as where I am confused at. Aren't I just supposed to solve for x at this point? The - seems to be throwing me off. Any explanation you can offer would be appreciated!
What is the force F on the 1.0 nC charge in the middle of Figure 2 due to the four othercharges? Give your answer in component form.Don't only do calculations but give a little explanation that i understand , plz
Compare the size of the electric fields of an infinite sheet of electric charge, an infinite charged plate, and infinite but oppositely charged parallel plates. Since we do not use calculus here, you can take the answers as going over some reference on your own but you need to understand how we can calculate the size of the electric fields using Gauss law. One of advantages of using the law is that we do not need to introduce calculus in order to estimate the electric field.
1. What is the electric field due to a point of 15μC at a distance of 1 meter away from it? 2. What is the electric field strength at a distance of 10 cm from a charge of 2μC? 3. What is the electric field strength at a distance of 130 cm from a charge of 5.2 μC?
In the figure below, q1 = 1.50××10^−7 C and q2 = 3.50×10^−7 C. 1)What is the x component of the electric field E⃗ E→ at the point (x, y) = (6.00 m, 3.00 m)? (Express your answer to three significant figures in N/C.) NOTE -- the figure is correctlylabeled in centimeters and the question is asking for the E-field at (6,3) meters. Account for this in your calculation. 2)What is the y component of the electric field E⃗ E→ at the point (x, y) = (6.00 m, 3.00 m)? (Express your answer to three significant figures in N/C.)
