Problem

A 5 kg5\,\text{kg} point mass is located at (3 m, 0)(3\,\text{m},\,0) and a 12 kg12\,\text{kg} point mass is located at (0, 4 m)(0,\,4\,\text{m}) in the xyxy-plane. Taking the origin at (0,0)(0,0), what is the magnitude of the net gravitational field at the origin? (a) 4.5×10−11 N kg−14.5\times10^{-11}\,\text{N kg}^{-1} (b) 6.2×10−11 N kg−16.2\times10^{-11}\,\text{N kg}^{-1} (c) 2.3×10−10 N kg−12.3\times10^{-10}\,\text{N kg}^{-1} (d) 8.7×10−11 N kg−18.7\times10^{-11}\,\text{N kg}^{-1}
