If you weigh 650 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 16.0 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.

1. The escape speed V is the minimum speedneeded to project a mass m upward from the surface of another
mass M (such as a planet, asteroid, or star). It is given by
v =√2GM
R

(a)Calculate the escape velocity v from the surface of the Sun.

USE:

M =1.99 × 1030 kg ,

G=gravitational constant 6.67 x10-11 N*m2/kg2

R =6.96 × 108m.

1. The escape speed Vis the minimum speed needed to project a mass m upward from thesurface of another

M = 1.99 × 1030 kg ,

G= gravitational constant 6.67 x10-11 N*m2/kg2

R = 6.96 × 108m. is the radius of thesurface from the center of M

a) Suppose the Sun mysteriously begins to contract. What would bethe radius for which v escape fromthesurface equals the speed of light c? [This radius is known as theSchwarzschild radius. Anything thrown from that surface willeventually fall back on the surface. Interestingly Newton’suniversal gravitation and Einstein’s general relativity predict thesame value fo the Schwarzschild radius.]

b) Find the Schwarzschild radius for Earth’s mass 5.97 ×1024 kg.

What is the value of the composite constant(Gme,/r2e) to be multiplied by themass of the object mo, in equation below:

Fg=G(mem0/r2e)=(Gme/r2e)mo

mo=object of mass sitting on surface,me=mass of earth, re=distance between objectand center of earth

earth has mass m earth=5.98 x 1024 kg, sun has mass msun=1.99 x 1030 kg,

r=93 million miles=150 million km
