A team of astronauts lands on the surface of a newly discovered planet in a different solar system. In this solar system, the star the planet orbits has a mass 1.5 times that of the Sun and a radius 2 times that of the Sun.

The planet the astronauts land on has a mass 1.2 times that of the Earth and a radius 1.7 times that of the Earth.

What is the magnitude of the gravitational field at the surface of the planet?

A

$6.92\quad \cfrac { m }{ { s }^{ 2 } }$

B

$4.07\quad \cfrac { m }{ { s }^{ 2 } }$

C

$7.36\quad \cfrac { m }{ { s }^{ 2 } }$

D

$23.63\quad \cfrac { m }{ { s }^{ 2 } }$
