Chapter 3: Q26P (page 124)

The mass of the Sun is The mass of the Earth is and their center-to-center distance is Suppose that at some instant the Sun's momentum is zero (it's at rest). Ignoring all effects but that of the Earth, what will the Sun's speed be after one day? (Very small changes in the velocity of a star can be detected using the "Doppler" effect, a change in the frequency of the starlight, which has made it possible to identify the presence of planets in orbit around a star.)

Short Answer

Expert verified

The value of force

Step by step solution

01

Identification of given data

Mass of sun

Mass of earth

Distance

02

Calculation of the gravitational force

According to the Newton鈥檚 low of gravitation

According to the Newton鈥檚 low of gravitation

Where

G 鈥� Gravitational constant

- Mass of 1 object

Mass of 2 objects

Distance between two object

So after putting the values we get

Thus, the value of force is
