Chapter 13, Problem 100P

In Fig. 13-57, identical blocks with identical masses m = 2.00 kg hang from strings of different lengths on a balance at Earth's surface, The strings have negligible mass and differ in length by h = 5.00 cm, Assume Earth is spherical with a uniform density ρ = 5.50 g/cm³. What is the difference in the weight of the blocks due to one being closer to Earth than the other?
