A Levels Physics

Exoplanets are planets orbiting stars other than our own Sun. Most exoplanets
discovered so far are giant planets similar to the planet Jupiter. The exoplanet Kepler-7b
has a mass about 0.43 times the mass of Jupiter, and a radius about 1.6 times the radius
of Jupiter.
Take the gravitational field strength at the surface of Kepler-7b to be gk, and the
gravitational field strength at the surface of Jupiter to be g₁.
