(A)what would you to determine the gravitational force between the two cows ?    asssume that g=10m/s^2.         (b)estimate in SI values for the quantities you would need to know and list your estimated values below.           (c) using the estimated valus=es ,compute the estimated  force of gravitional attraction between the cows.show calculations.l=you may leave the ansewr in scientific notation

The force due to gravity between two objects is given by Newton's law of universal gravitation as:

`F = (Gm_1m_2)/R^2`

In order to calculate the gravitational force of attraction between the two cows on Earth, the following quantities are needed to be known:

1. Mass of cow(1) in kg.

2. Mass of cow(2) in kg.

3. Distance between the cows in meters.

4. Value of G, the universal gravitational constant.

One practical estimate of the required quantities is listed below:

1. Mass of cow(1) =300 kg.

2. Mass of cow(2) =240 kg.

3. Distance between the cows in meters=30.

4. 6.673*10^-11 n-m^2/kg^2
