Gravitational field strength
A planet in a mass spectrometer trial has mass \(7\times10^{24}\,\text{kg}\). A probe is \(7\times10^{6}\,\text{m}\) from its centre. Use \(G=6.67\times10^{-11}\). Calculate gravitational field strength. Enter the numerical result and choose the interpretation that matches the field physics.
