Question

Neutron stars, such as the one at the center of the Crab Nebula,
have about the same mass as our sun but a *much* smaller
diameter.

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 21.0 km ?

Take the mass of the sun to be *m*s =
1.99×10^{30} 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 *w*star in newtons.

Answer #1

weight on earth

W = m g

m = W / g

= 690 / 9.8

= 70.408 kg

if the person with mass m = 70.408 is om the surface of the nuetron star then the gravitational force of attraction between person and the nuetron star will be

Fg = G m_{1} m_{2} / r^{2}

where

G = 6.67×10^{−11} N⋅m2 / kg^{2}

m_{1} = 70.408 kg,

m_{2} = 1.99×10^{30} kg

r = 10.5 km

Fg = = m_{1} g

m_{1} g = G m_{1} m_{2} /
r^{2}

the acceleration on the surface of neutron star is

g = G m_{2} / r^{2}

= (6.67×10^{−11}) (1.99×10^{30}) / (10.5 x
10^{3})^{2}

^{ } = ......... m / s2

the weight on the neutron star will be

W = (m_{2}) g

= ......... N

Neutron stars, such as the one at the center of the
Crab Nebula, have about the same mass as our sun, but a much
smaller diameter.
If you weigh 650 N on the earth, what would you weigh on the
surface of a neutron star that the same mass as our sun and a
diameter of 20.0 km?

Neutron stars, such as the one at the center of the Crab Nebula,
have about the same mass as our sun, but a much smaller
diameter.
Part A
If you weigh 700 N on the earth, what would you weigh on the
surface of a neutron star that has the same mass as our sun and a
diameter of 20.0 km?

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 22.0 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 free-fall acceleration at the earth's surface to
be g = 9.8 m/s2 .
Express your weight wstar in newtons.

Astronomers detect stars that are rotating extremely rapidly,
known as neutron stars. A neutron star is believed to form from the
inner core of a larder star that collapsed, under its own
gravitation, to a star of very small radius and very high density.
Before collapse, suppose the ore of such a star is the size of our
Sun (R = 7105km)with mass 2.0 times as great as the Sun, and is
rotating at a frequency of 1.0 revolution every...

Neutron stars are one of the possible “final states” of a star.
The idea is that for a sufficiently massive star, the gravitational
pressure is enough to overcome the outward pressure (that comes
from essentially the Pauli exclusion principle) that keeps fermions
from coinciding with each other.
Part A) According to quantum statistics, the OUTWARD pressure of
a (neutron) fermionic gas is given by P=[(3.9?^2)/(2m)](N/V)^(5/3),
where m is the mass of a neutron, and N/V is the number density of...

uring a solar eclipse, the Moon is positioned directly between
Earth and the Sun.
The masses of the Sun, Earth, and the Moon are 1.99×1030
kg,1.99×1030 kg, 5.98×1024 kg,5.98×1024 kg, and 7.36×1022

A neutron star has a mass of 2.0 × 1030 kg (about the
mass of our sun) and a radius of 5.0 × 103 m (about the
height of a good-sized mountain). Suppose an object falls from rest
near the surface of such a star. How fast would this object be
moving after it had fallen a distance of 0.017 m? (Assume that the
gravitational force is constant over the distance of the fall and
that the star is not...
