ion B: Two objects of the same mass are situated at different height. 10 kg 3 10 kg 10 m attachme The potential energy of the that is 10 m from the grour twice as much the pote energy of the box that is 5 m. the ground when both boxes of the same mass. Why is this so? The box that is 10 m from ground has twice as much he of the other box. Since mass is same for both boxes, using formula of potential energy. PE = mgh -mg(2h) Therefore, PE = 2mgh. The potential energy is doubled.​
