Force and Potential Function (80 points). Consider the case in which the relationship betwern a force field, F(x,y,z), and the potential function, V(x,y,z), of a moving particle is given byF(x,y,z)=-gradV(x,y,z)Since V is a potential fanction, it is scalar-valued and has cotetinuous partial derivatives. Show that the work done in moving a particle from one point r1=(x1,y1,z1) in this force feld to another point r2=(x2,y2,z2) is independent of the path jolning two polints.Hint: Note that is this case, the differential of work is given by
