If you weigh 660 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun an

Arada [10]

Answer:

8.93*10^13 N.

Explanation:

Assuming that in this case, the weight is just the the force exerted on you by the mass of the star, due to gravity, we can apply the Universal Law of Gravitation:

$F_{g}= \frac{G*m_{1}*m_{s}}{r_{s}^{2} }$

where, m1 = mass of the man = 660 N / 9.81 m/s^2 = 67.3 kg, ms = mass of the star = 1.99*10^30 kg, G= Universal Constant of Gravitation, and rs= radius of the star = 10.0 km. = 10^4 m.
Replacing by the values, we get:

$F_{g}= \frac{6.67e-11Nm^2/kg^2*1.99e30 kg*67.3 kg}{10e4m^2} = 8.93e13 N$

Fg = 8.93*10^13 N.
