Answer:
The Roche limit for the Moon orbiting the Earth is 2.86 times radius of Earth
Explanation:
The nearest distance between the planet and its satellite at where the planets gravitational pull does not torn apart the planets satellite is known as Roche limit.
The relation to determine Roche limit is:
....(1)
Here is radius of planet and
are density of planet and moon respectively.
According to the problem,
Density of Earth, = 5.5 g/cm³
Density of Moon, = 3.34 g/cm³
Consider be the radius of the Earth.
Substitute the suitable values in the equation (1).
Number 3.
When you have two parallel wire and the charges are moving, they create a magnetic field around the wire (right-hand rule, thumb points in the direction of current).
If you want the math, here ya go:
F: magnetic force on the wire, L: length of the wire I: current in one wire I': current in other wire r: distance of the wire.
As we can see, two wires that has current through it will generate a force on each other.
