A smaller than F If the magnitude of the gravitational force of Earth on the Moon is F, the magnitude of the gravitational force of the Moon on Earth is

Force of Moon on Earth =

Explanation:

The Newton's Law of Gravitation gives the magnitude of the force of attraction between two masses due to gravitational force. The formula is given as below:

where,

G = Universal Gravitational Constant

m₁ = mass of body 1

m₂ = mass of body 2

r = distance between the masses

F = Force of attraction between the objects

The magnitude of force applied by the objects on each other are equal but opposite in direction.

Therefore, if the force of Earth on Moon is F.

Then, the force of moon on earth will be:

Force of Moon on Earth = - F

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
