Homework Statement
Two masses are connected by means of a string which passes over a light frictionless pulley. The coefficient of kinetic friction between the 9kg mass and the table is 0.25. The applied force on the 9kg mass is unknown and the acceleration of the unknown mass, m, is 1m.s^2...
A charge of 1.2x10^-3C is fixed at each corner of a rectangle that is 30cm wide and 40cm long. What is the magnitude and direction of the electric force on each charge? What is the electric field and the electric potential at the centre?

Multiple Point Charges
Alright so the question is:
A charge of 1.2x10^-3C is fixed at each corner of a rectangle that is 30cm wide and 40cm long. What is the magnitude and direction of the electric force on each charge? What is the electric field and the electric potential at the centre?

This is not homework. This is going through a textbook for an exam i have at the end of the year. Its basically teach yourself and i don't have a teacher to ask and i don't know where to start with this problem.. All i know is that the electrical field lines are driven away from positively...
If anyone would like a go at this problem, they can just attach a paint file or something or send it to my e-mail:
Heres the problem:
9. Three small, negatively charged spheres are located at the vertical of an equilateral triangle. If the magnitudes of the charges are equal, sketch the...
