Hello, i hope i posted this in the correct section.. I have a question: the potential energy of a body when it is at point P a distance x from a reference point O is given by V = kx^2, where k is a constant. what is the force acting on the body when it is at P? the correct ans is 2kx in the direction of PO the ans i got is kx in the direction OP. as work = force x distance, so force required to bring the body to point p is kx^2 / x . could some please explain why is the correct ans so? thnk u so much!!
