What factors affect the strength of the electric force between two objects
Nady [450]
There are three factors:

The charge of the two objects. The electric force is proporcional to the product of the charges of both objects.

The distance that separetes them. The electric force is proportional to the inverse of the squared distance that separates the objects.

The media. The electric force constant of proportionality depends on the media: air, water, oil, glass.

the andromeda galaxy is approaching our galaxy with a radial velocity of 120 km/s. given the galaxies present separation of 800
Nookie1986 [14]

The andromeda galaxy is approaching our galaxy with a radial velocity of 120 km/s. given the galaxies present separation of 800 kpc, and neglecting both the transverse component of the velocity and the effect of gravity in accelerating the motion, estimate when the two galaxies will collide.

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy that is 2.5 million light-years away from Earth and the closest big galaxy to the Milky Way. It has a diameter of roughly 46.56 kiloparsecs.

The Milky Way, which houses the Solar System and Earth, and the Andromeda Galaxy are anticipated to collide in roughly 4.5 billion years. This galactic collision will take place between the two largest galaxies in the Local Group. The Andromeda galaxy is the brightest galaxy outside of our solar system. It is the furthest object that the majority of us humans can see with our unaided eyes at a distance of 2.5 million light-years.
