Thank you all for working so hard on the assignment yesterday. There’s a new, similar assignment today. Only 3 problems, but much more difficult (and worth considerably more points.)
Some hints for today:
First μ is a prefix meaning micro, or 10^-6. So when you see 5.7μC, we’re talking about 5.7*10^-6 coulombs
Second, remember all of your rules about vectors, vector addition, and how to combine vectors from 2 dimensions into 1.
A really helpful tool: Hyper Physics Coulomb Force Calculator
For an Electric Field calculation, Q2 is usually just a single electron, or a single proton. Use the calculator above, then divide the answer you get by the charge of that single electron.
