Homework Statement I am given 5 distances to place the object relative to the lens. I then need to calculate each of the images distances for all 5 and record them. Once I have that done, I am to conduct a graph of 1/q vs 1/p. I then need to answer these questions: 1- Is the slope of your...

I see my error, thank you guys very, very much for the help! Can't thank you enough!

so if its V=(1E-3)(100,000) = 100 v across the resistor its 100 V across the voltmeter for part a? For b you then take 100v=I(10E7) = 1E-6 A?

Well given 1ma over the resistor you can do V = (1E-3)(100,000) which is the voltage drop over the resistor...without the total voltage how can I find the voltage drop over the volt meter? current through voltmeter?

Homework Statement Voltmeter has a internal resistance of 10M ohms and the resistor has a resistance of 100,000ohm. The current through the resistor is 1mA. a)What is the voltage drop across the voltmeter? b)What is the current through the voltmeter? Homework Equations V=IR is all you...

oops was cosine. Thank you!

Im completely lost how this is not right. The first answer is right for sure.

SOLVED! Thank you!

SOLVED! Thanks!

I know its not right because with it marked true, it was my very first response (the above answers with 3 being true.) I thought that was right to begin with but its not.

even if number three was true, its still not all right?

Wrote them above.

Homework Statement 2. Relevant thoughts Here, I numbered them down and put why I though those answers were what I have above 1- since 0V, its PE is zero 2- Closest contour lines, largest charge 3- Q1 is farther back from 0v, making it the largest negative 4- above 0V so it has a positive...

so the answer should be negative then? I am still having trouble ugh.

Homework Statement An electric point charge of Q1 = 5.23 nC is placed at the origin of the real axis. Another point charge of Q2 = 1.89 nC is placed at a position of p = 2.63 m on the real axis. At which position can a third point charge of q = -2.62 nC be placed so that the net...
