Answer:
8.29 * 10^{13} N
Explanation:
Weigth is the force of gravity a body of mass experiences due to the gravity of another mass.
Force=mass*acceleration (to calculate the mass of the object);
675=m*9.8; Mass = 68.88 kg
Force= [tex]\frac{GMm}{r^{2} }[/tex]; M is the mass of the bigger object, m is the mass of the smaller object, r is the seperation in between (radius in this case) and G is the Gravitational constant.
Mass of the sun = 1.989 × 10^30 kg
G = 6.67 × 10-11 m3 kg-1 s-2
mass of the object = 68.88 kg;
Applying the formula:
Force=[tex]\frac{(6.67 * 10^{-11} ) * (68.88) * (1.989 * 10^{30} )}{(((21 *10^{3} ))/2)^{2} }[/tex]
Force = 8.29 * 10^{13} N
The weight on the surface of a neutron star that has the same mass as our Sun and a diameter of 21.0 km will be 8.29 × 10¹³ N
Gravitational force:
Given that the weight of the person on the earth is 675N.
mg = 675N
where m is the mass of the person.
m = 675/g
m = 675/9.8
m = 68.87 kg
The gravitational force on the surface of a celestial body is given by:
F = GMm/R²
where G is the gravitational constant
M is the mass of the body
m is the mass of the person
and, R is the radius of the body
F = (6.67 × 10⁻¹¹)( 2 × 10³⁰)(68.87) / (21/2 × 10³)²
F = 8.29 × 10¹³ N
