The amount of gravitational force between both objects will be the same.
The magnitude of the Earth's gravitational force exerted on the housekeeper is calculated by applying Newton's second law of motion;
F = mg
where;
<em>m </em><em>is the mass of the housekeeper</em>
<em>g </em><em>is acceleration due to gravity</em>
According to Newton's third law of motion, action and reaction are equal and opposite.
The force exerted on the housekeeper by the Earth is equal in magnitude to the force exerted on the Earth by the housekeeper.
The two forces are equal in magnitude but opposite in direction.
Thus, the correct option is " the amount of gravitational force between both objects will be the same"
<em>The</em><em> missing part</em><em> of the </em><em>question </em><em>is below:</em>
a. the Earth exerts the largest amount of gravitational force
b. the housekeeper exerts the largest amount of gravitational force
c. the amount of gravitational force between both objects will be the same

Answer:
a. The refractive index ranges from 1.5 - 1.56
b. 18.7° for violet light and 19.5° for red light.
c. 33.7° for violet light and 35.3° for red light.
Explanation:
a. The refractive index of an object is the ratio of the speed of light in a vacuum and the speed of light in the object.
Mathematically,
The speed of violet light in the object is .
The speed of red light in the object is
Hence, the refractive index for violet light is:
and for red light, it is:
Hence, the refractive index ranges from 1.5 - 1.56.
b. The refractive index is also the ratio of the sine of the angle of incidence to the sine of the angle of refraction.
The angle of incidence is 30°.
The angle of refraction for violet light will be:
And the angle of refraction for red light will be:
The angle of refraction for red light is larger than that of violet light when the angle of incidence is 30°.
c. The angle of incidence is 60°.
The angle of refraction for violet light will be:
And the angle of refraction for red light will be:
The angle of refraction for red light is still larger than that of violet light when the angle of incidence is 60°.
