This problem has been solved! It does not depend on the magnitude of the small sample mass. For example, if you say that an elevator is moving upwards with the acceleration of 0.2g , it means that it accelerates with about 6.2 ft/s or 2 m/s (i.e., 0.2 g ). (As planets and natural satellites form pairs of comparable mass, the distance 'r' is measured from the common centers of mass of each pair rather than the direct total distance between planet centers. Using this principle, the given equation will have the same dimension on both sides. g&=\sqrt{\dfrac{6.67\times 10^{-11}\;\rm m^3/kg.s^2\times 8.68\times 10^{25}\;\rm kg}{\left ( 2.33\times 10^{7}\;\rm m\right )^2}}\\ Uranus is an ice giant (instead of a gas giant). The radius of Uranus is about 2.33 \times a. The smallest period is when the acceleration due to gravity (g) is the largest. Since All are of Dimension L , the result of sum is also equal to L.
