How does the gravitational force between two objects change if the distance between the objects doubles?
Ymorist [56]

if the distance between the objects is doubled the force is reduced by a factor of 4

<h3>Whats is gravitational force?</h3>

Gravitational force is the force of attraction between objects in the universe.

f = G * m1 * m2 / r^2

f = gravitational force

G = gravitational constant

m1 = mass of object 1

m2 = mass of object 2

r = distance between the objects

From the formular, the gravitational force and the distance is an inverse relationship so increasing the distance by a factor results to reduction of the force by the square of the factor. hence doubling the distance which is distance mutiplied by 2 will lead to reduction of the force by 2^2 = 4

Therefore: The force decreases by a factor of 4.

hope it helps

A U-shaped tube open to the air at both ends contains water. A quantity of oil of unknown density is slowly poured into the righ
nadezda [96]

Answer:

\rho_o=600\ kg.m^{-3} is the density of the oil

Explanation:

Given:

  • height of oil column, h_o=20\ cm
  • oil column height that is more than the water column height in the other arm, \delta h=8\ cm

<u>Now from the given it is clear that the height of water column is:</u>

h_w=h_o-\delta h

h_w=20-8

h_w=12\ cm

Now according to the pressure balance condition of fluid columns:

Pressure due to water column = Pressure due to oil column

P_w=P_o

\rho_w.g.h_w=\rho_o.g.h_o

1000\times 9.8\times 0.12=\rho_o\times 9.8\times 0.2

\rho_o=600\ kg.m^{-3} is the density of the oil
