1. Two electric charges, the first value + 3Q and the second value + 2Q are separated by a known distance d. What load and at what distance from the first load should a third collinear load be placed with the other two, so that the three-load system is in equilibrium?
2. What is the force exerted on the load Q of the corner of a cube of side a, if in each corner of the cube there are loads of value Q (In total there are 8 loads in the cube)?
3. At point (0, a) there is a load + 2Q and at point (b, 0) a load of value -3Q. What is the value of the electric field (as a vector) at the following points: (a, a), (b, b), (0,0)?
