I think the situation is modeled by the scenario in the attached image. Some specific values seem to be missing (like the height of door )...
The door forms a right triangles that satisfies
We also have
so if you happen to know the height of the door, you can solve for and
.
is fixed, so
We can solve for the angular velocity :
At the point when and
ft/s, we get
Answer:
The magnitude of the electrostatic force is 120.85 N
Explanation:
We can use Coulomb's law to find the electrostatic force between the down quarks.
In scalar form, Coulomb's law states that for charges and
separated by a distance d, the magnitude of the electrostatic force F between them is:
where is Coulomb's constant.
Taking the values:
and knowing the value of the Coulomb's constant:
Taking all this in consideration:
