I'm insulted. Yes, I know what an equilateral triangle is. It has three sides of equal length, and all three angles are 60 degrees. As I stated, I found the net force on two of the points, but Q(1) is giving me issues. Obviously the way I'm trying is wrong, so I'd like help, thank you.

Likewise, this similar problem also has me stumped A charge of 7.00 mC is placed at each corner of a square 0.80 m on a side. Determine the magnitude of the force on each charge. Any help would be greatly appreciated!

ooh yikes, thank you, I didn't notice that. And I drew the vector diagram too, so I should've realized lol. Thank you!

Hello, I'm in the middle of a problem on the online program Webassign, trying to calculate the coefficient of friction in a problem. I have the correct value of the force of friction, and I believe I have the correct Normal Force value, but the program is rejecting my answer. The problem...

ok thank you, it's just that my teacher never showed us what the third plane looks like, so I was confused as to how it relates to the x and y planes on a grid. thanks again.

Sorry to have posted this twice, but I didn't realize there is a special homework help section until after I'd posted in another part of the board. Anyway, any guidance in how to draw the diagram for the following problem would be greatly appreciated. I'm not sure about the position of the Z...
