Homework Statement Show the mathematical relationship between magnetism and electricity by looking at constants Homework Equations I have several equations but in don´t really know which one I have to use and I don´t see any big similarities except that there is force, charge, velocity...

The teache or the problem didn´t say it but on the picture that I got it looks like there is a right angle, where Proton B is.

Hi, There are 3 Protons (P) that form a triangle. distance PA-PB -->15mm distance PB-PC -->20mm distance PA-PC --> unknown I have to calculate the last distance and the forces between the protons by using coulomb´s laws. I tried to calculate the force between AB and BC: F1=1.02 E...

Can I just plug it in the equation: T²=R³ ?

Hi, I have a question about orbiting objects. Maybe somebody could help me a little bit, because I don't know if I need to find other information to solve the problem and I'm not sure what equation I could use. If the average orbital radius is 2,5*1025 km, how long will it take to orbit the...

Does 75N sound better? If it's correct, I think I know what I did wrong. If I'm right I just have to divide the force twice by two instead of deviding it by three. Otherwise please explain me how I can solve these kind of problems because our teacher did not.

Hi, I have to do the Nellie Newton Problems on this Page here: Link! We just started with Forces and I tried to solve the problems but I´m not completely sure if my answers are correct. If there are mistakes it would be nice if you could tell me why and what I did wrong. Here are my...
