Given are the 3 charges: q1 = +10 µC, q2 = +20 µC, q3 = - 30 µC. All 3 are located at x = -1.0 m, at the origin.and at at x = +2.0 m, respectively. Find the Net Force on q2.

Given are the 3 charges: q1 = +10 µC, q2 = +20 µC, q3 = - 30 µC. All 3 are located at x = -1.0 m, at the origin.and at at x = +2.0 m, respectively. Find the Net Force on q2.A. 3.15 N to the positive x- direction

B. 2.50 N to the negative x- direction

C. 3.3 N to the negative x-direction

D. 5.60 N to the positive x- direction

Referring to the problem above, Calculate the magnitude of the net electric field at(+1.0 m, 0) due to the 3 given charges.A. 189, 562 N/C

B. 386, 438 N/C

C. 675,500 N/C

D. 472,500 N/C

How about these other 2 problem? 1. There are 2 charges, q1=6.9 nC and q2=4.20 nC. Located at X=80cm and at X=80 cm, respectively. Calculate the net electrical potential at the origin by these charges. A. 0 B. 125V C. 22.5kV D. 45kV 2. Under a high-tech microscope, a scientist is studying 2 protons in the nucleus of a Uranium atom. He noted that they are 9fm apart. What is the potential energy (in J) associated with the electric force that acts between these two particles? Please help me, too, with this. Thank you very much!

Do you mind posting these questions publicly? I think I can answer them better with another video :)

Also I believe I answered #1 in a separate video :)

Oh, don't worry, I already answered it. But could you help me with another one? It has nothing to do with solving. But we are tasked to do a video demonstration of attraction and repulsion of charges using common school/household items. Include the explanation of the laws that demonstrate the phenomena. I hope you can help me with this one. I know it's very easy and simple, but I'm currently super loaded with schoolwork and working on my group research at the same time. So I'm having a hard time managing my time. And again, thank you very much for your help and keep safe :)
