Planet Z-34 has a mass equal to one-third that of Earth and a radius equal to one-third that of Earth. With g representing, as usual, the acceleration due to gravity on the surface of Earth, the acceleration due to gravity on the surface of Z-34 is

Respuesta :

Answer:

The acceleration due to gravity on the surface of Z-34 is equal to  [tex]3g[/tex] .

Explanation:

Here we know that acceleration due to gravity on a planet of mass M and radius R is given by  

     [tex]g = \frac{GM}{R^{2}}[/tex]

Given that mass of earth is M and radius is R .

  Mass of Z-34 = [tex]\frac{M}{3}[/tex] ,

  Radius of Z-34 = [tex]\frac{R}{3}[/tex]

 G = gravitational constant .

   [tex]g_{z}[/tex] = acceleration due to gravity on Z-34 ,

          [tex]\frac{g}{g_{z}} = \frac{M}{\frac{M}{3} } \times (\frac{\frac{R}{3} }{R})^{2} = \frac{1}{3} \\ \\g_{z} = 3g[/tex]
