The Joint Force Air Component Headquarters (JFACHQ) is the United Kingdom's deployable air command and control unit. The JFACHQ is run by the Royal Air Force with representation from the other services.The JFACHQ has members from the operations and operations support branches of the RAF to both plan and execute the air war as well as support the deployed air components from A1 to A9.
The unit is based at RAF High Wycombe. It can deploy worldwide at short notice to run an air campaign.
The constituent parts of the JFAC are broken down according to the Continental staff system:
A1 – PANDA (Personnel and administration)
A2 – RAF Intelligence
A3 – Air operations (both plans and current operations)
A4 – Air logistics
A5 – Air strategy and contingency planning
A6 – Air CIS (Communication and Information Systems)
A7 – Air training
A8 – Finance and budgets
A9 – POLAD (Political advice) and LEGAD (Legal adviser)
I do not understand why the tan component for a gravity affected by the centrifugal force:
g = Ω^2 * R * sinθ * cosθ
So I tried to draw this: using a "big" X-shaped axis where the / component goes along the main gravity direction while \ points normal to / this direction. Then the centrifugal...

A Rod of Mass "M" is attached to a two-way hinge on the floor. It is being pulled by a spring (extension spring, so force is pulling the rod to the right, causing it to move clockwise).
The hinge is frictionless.
the rod has a mass of 5kg evenly distributed
the pulling...

Consider the figure below, we need to find the charge on Q_0, both charges Q are negative. It is given that the net charge on Q_A is zero.
The figure of the problem is attached.
The Attempt at a Solution
I understand how to get the solution except for one part. I'm just...
A charge Q is placed at a distance a = 3m and a charge q is placed at a distance b
For what value(s) of b is the x-component of the force maximized?
I know to maximize the force we need to maximize F_Qq = k Qq b/(3^2 + b^2)^{3/2}.
To do this we need to set the first derivative to zero and...
