The acceleration due to the gravity of the earth is 9.8 m/s^2. if the mass of jupiter is 319 times the mass of the earth and its radius is 11 times the radius of the earth. Calculate the acceleration due to gravity of jupiter. What is the weight of an object of mass 100 kg on jupiter?



Answer :

Answer:

  • the acceleration of gravity of Jupiter = 25.836 m/s²
  • the weight of mass 100 kg on Jupiter = 2583.6 N

Explanation:

To find the gravity of Jupiter, we can compare it with earth's gravity by using this formula:

[tex]\boxed{g=\frac{Gm}{r^2} }[/tex]

where:

  • [tex]g=\text{gravitational acceleration}[/tex]
  • [tex]G=\text{gravitational constant}[/tex]
  • [tex]m=\text{mass}[/tex]
  • [tex]r=\text{radius}[/tex]

Given:

  • [tex]g_e=9.8\ m/s^2[/tex]
  • [tex]m_j=319m_e[/tex]
  • [tex]r_j=11r_e[/tex]

Hence:

[tex]\displaystyle g_e:g_j=\frac{Gm_e}{r_e^2} :\frac{Gm_j}{r_j^2}[/tex]

[tex]\displaystyle 9.8:g_j=\frac{m_e}{r_e^2} :\frac{319m_e}{(11r_e)^2}[/tex]

[tex]\displaystyle 9.8:g_j=1 :\frac{319}{121}[/tex]

[tex]\displaystyle g_j=\frac{319}{121}\times9.8[/tex]

[tex]\bf g_j=25.836\ m/s^2[/tex]

To find the weight of an object of mass 100 kg on Jupiter, we can use this formula:

[tex]\boxed{weight(w)=mass(m)\times gravitational\ acceleration(g)}[/tex]

[tex]w_j=m\times g_j[/tex]

    [tex]=100\times25.836[/tex]

    [tex]=2583.6\ N[/tex]
