Answer

Explanation

Solution

As g=GMgRE2∴ gG=MERE2\mathrm { g } = \frac { \mathrm { GM } _ { \mathrm { g } } } { \mathrm { R } _ { \mathrm { E } } ^ { 2 } } \therefore \frac { \mathrm {~g} } { \mathrm { G } } = \frac { \mathrm { M } _ { \mathrm { E } } } { \mathrm { R } _ { \mathrm { E } } ^ { 2 } }
