Technically, all of the forces acting on the charge are opposite another- so by that logic, wouldn't they all cancel out? I truly do not understand. :-(

Homework Statement Three positive particles of charges +7.0 uC are located at the corners of an equilateral triangle of side 20 cm. Calculate the magnitude and direction of the net force on each particle. Answer: 19.0 N [AWAY FROM THE CENTRE] Homework Equations F = (kQ1Q2)/(r^2)...

Thank you! It was very thorough, and easy to understand! :)

Also, if someone could help me out as to the direction of each E. Field where I note (Not Sure of Direction), that would be great as well!

Determining Direction of Electric Field! :) Homework Statement Calculate the electric field at one corner of a square 50 cm on a side if the other three corners are occupied by 250 x 10^-7 C charges. Homework Equations E = (kQ)/(r^2) Where: E = Electric Field Intensity in (N/C)...

No, I actually haven't.

Homework Statement Question: Four 8.0 kg spheres are located at the corners of a square of side 0.50m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three. Answer from Back of Textbook: 3.3 x10^-8 N toward diagonally opposite sphere...
