The work done by a system on a different body is equal to the product of the force exerted and the distance that the body has move in parallel to the force exerted. In this item, we have to determine first the distance and multiply it with the given force equal to 750N.

Explanation:
Answer:
Given:
The distance of the star is,=4.29 ly
We know that one light year is the distance travelled by light in one year.
1 light year = 3×10
8
×365×24×60×60
=94608×10
11
m
Therefore, the distance in 4.29 ly can be written as:
4.29 ly=405868.32×10
11
m
We know that 1 Parsec is also the unit of distance and its value is:
1 parsec=3.08×10
16
m
Now, to express the distance in terms of parsec.
4.29ly=
3.08×10
16
405868.32×10
11
=1.32 parsec
The diameter of the Earth's orbit is,
d=3×10
11
m
The angle made by the star on the Earth's orbit can be given by:
θ=
405868.32×10
11
3×10
11
=7.39×10
−6
rad
But, the angle covered in 1sec=4.85×10
−6
rad
So, the parallax in viewing the star at two different positions of the Earth's orbit:
for, 7.39×10
−6
rad=
4.85×10
−6
7.39×10
−6
=1.52"
