The planets near the sun are smaller (and made out of rock or earth )
Use the formula. Plug in known values, so you get f = 3000*2 and get 6000N as a result.
Answer:
No, it is not necessary for them to have same mass.
Explanation:
Let both bodies have a density d1 and d2 respectively.
Since their volumes are equal V1 = V2
we know that, https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%7D
Hence, d1 = and d2 =
Taking the ratio of densities,we get
This implies that unless the bodies have same densities, the mass of the two bodies will not be same.
Speed is how fast and object moves and velocity is a variable that tells you both speed and direction
