a charged particle is in point (2, 3, 8) and has a charge Q1 = 5x10-10C. Another particle is at (5,7,0) and has a charge Q2 = 3x10-10C. Calculate how much work needed to move the first particle to the point (0, -7.2) using the electric field

And regarding the position of the charges it only says its positions in the room for example charge 1 is : (x,y,z) = (2,-3,8). But it should be in Meters if SI-unit is needed..

I need to calculate this using the integral formula which is: W = - ∫ F dl = - q ∫ E dl Where E = 1 / 4piε0 * R(vector) / R^3 I am just confused in what E-field I have to use and do I need to calculate X,Y & Z separately??
