Question

If you weigh 690 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 24.0 km ?

Take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be G = 6.67×10−11 N⋅m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 .

Express your weight wstar in newtons.

Answer 1

Step-by-step explanation:

Why is earth gravity reported to 4 significant digits when all the other data are reported to only 3???

Gravity on the neutron star would be

g' = GM/d²

g' = 6.67 x 10⁻¹¹(1.99 x 10³⁰) / 24000²

g' = 2.30 x 10¹¹ m/s²

Fs = Fe(g'/g)

Fs =690(2.30 x 10¹¹ / 9.81)

Fs = 1.62 x 10¹³ N

which means you would be an exceedingly thin crispy layer of charred butter on the surface of such star.
