A 12.0 kilogram mass weighs 84.0 newtons on a newly discovered planet. What is the magnitude of the acceleration due to gravity on this planet?


A) 1.20 m/s^2


B) 7.0 m/s^2


C) 9.8 m/s^2


D) 84 m/s^2

The weight is the mass times the acceleration due to gravity

   

      [tex]Weight = mass*acceleration-due-to-gravity\\\\84N = 12kg* acceleration-due-to-gravity\\\\acceleration-due-to-gravity = 84N / 12kg\\\\acceleration-due-to-gravity = 7.0 m/s^2[/tex]

Thus the acceleration due to gravity is 7.0m/s^2.

Hope that helped!
