Weight is another term for the force from mass multiplied by acceleration due to gravity, the equation being expressed as , being force, mass, and acceleration respectively.

We already have 2 parts of the equation, 

Acceleration due to gravity on the planet is

Plug it into the equation

x 

Weight or force from gravity is 60N.
