Answer:
The force is inversely proportional to the square of radial distance and the mass of the lemon is compensated.
Explanation:
- It is true that our body is composed mostly of water (precisely 75% of the body mass) which is influenced by the gravitational forces. This gravitational force in the water bodies cause tides.
We know that mathematically gravitational force is given as:
where:
R = radial distance between the masses
we observe that:
The force is inversely proportional to the square of radial distance.
- And the radial distance between the moon and a human on the earth is much greater than the distance between a lemon of low mass on the head of a human.
You can tell if vector is an unit because it has something to do with taking the magnitude of the vector.
also has a length 1. thus you should use pythagoras to check.

Below is the answer:
W = mg
<span>W = ? </span>
<span>m = 670 </span>
<span>g = ? </span>
<span>radius of Neutron star = 11.5 km = 11,500 meters </span>
<span>We need to find g on the Neutron star, so: </span>
<span>g = GM/r^2 </span>
<span>g = 6.67 x 10^-11 x 1.99 x 10^30/11,500^2 </span>
<span>g = 1 x 10^12 </span>
<span>W = 670 x (1 x 10^12) </span>
<span>W = 6.7 x 10^14 N
</span>
