Explanation:
Detailed explanation-1: -So 500 g is just 0.5 kg. Then multiply that by 9.8 which is G. And then multiply that by 1.5 m and that should get you a value of 7.35 jews. So this ball of 500 rounds being lifted up 1.5 m gains 7.35 jewels of gravitational potential energy.
Detailed explanation-2: -Thus h = 1/5 = 0.2 m, Which is the required height.
Detailed explanation-3: -Potential Energy = mgh = 10 kg x 9.8 ms-2 x 10 m = 980 J.
Detailed explanation-4: -Hence the potential energy is . 6 kg jewels.
