i guess first i need to calculate the net force for the whole system and then i can find the work done ,,, what is confuse me is .. E=(x^x+y^2y+z)

Hi tiny-tim In fact i have to submit my assignment after 6 hours from now ... i tried to solve it .. and i don't know how to start to solve the question :( ... i don't want to get zero :( ... could you please help me

what is the work done by electric forces in moving a charge Q=1 nC from the origin to the point (1m, 1m, 1m) in the electrostatic field given by E=(x,y,z) = (x* (a sub x) + y^2*(a sub y) - (a sub z) V/m in the Cartesian coordinate system along the straight line joining two points?
