For below problems, express your answer in scientific notation
and with units where appropriate. Show all work to get credit. Use
the solar system data sheet. Universal Gravitational Constant: G =
6.674 x 10-11 m^2/(kg∙s^2 )
1) A star you are observing from the Earth is found to have a
parallax of 0.5 arcsec. How far away is this star?
2) What is the force of gravity between you and the white dwarf
Sirius B? The mass of Sirius B is about 1.02 times the Sun. Assume
its radius is same as the Earth. How does this result compare to
the force of gravity between you and the Earth which you calculated
in Homework 5? What do you think will happen to you if you visited
such a place?
PLEASE ANSWER THE QUESTION ABOVE ONLY
DO NOT ANSWER TO THE QUESTION BELOW
HW 5: The Kuiper cloud, also known as the Kuiper belt, is a
disk-shaped area visible beyond Saturn's orbit that contains a
large number of planets. The Oort cloud is a swarm of trillions of
comets and dust particles that orbit the sun in a circle. Even
though the Oort cloud is not technically a cloud, it reaches three
light years from the sun in all directions. For the problems below,
you may find useful the Solar System Data Sheet posted on
Blackboard. Universal Gravitational Constant: G = 6.674 x 10-11

average person whose mass is 62kg while he/she is standing on the
Moon. Similarly, find the force of gravity acting on an average
person whose mass is 62kg while he/she is standing on the
Earth.
