how to know the raiuds in GMm/r2?
To understand how to get the radius in the equation GMm/r^2, let's break it down step by step:
1. Understand the equation: GMm/r^2 is known as the force of gravity equation. It represents the gravitational force between two objects, where G is the gravitational constant, M and m are the masses of the two objects, and r is the distance between the centers of their masses.
2. Rearrange the equation: To find the radius, we need to rearrange the equation. Start by multiplying both sides of the equation by r^2:
GMm = (r^2) * (force of gravity)
Now, we have an equation where GMm is equal to the product of the radius squared and the force of gravity.
3. Calculate the radius: If you want to find the radius, you need to know the values of GMm and the force of gravity. If you have these values, you can divide both sides of the equation by the force of gravity:
(GMm) / (force of gravity) = r^2
Finally, take the square root of both sides to get the radius:
r = √[(GMm) / (force of gravity)]
To know the radius in the equation GMm/r^2, you need to have the values of GMm and the force of gravity between the two objects. Once you have those values, you can follow the steps mentioned above to calculate the radius.
