A spacecraft spins about its axis. What would be the feeling of an astronaut inside it?

If earth stop spinning about its own axis, what will be the change in acceleration due to gravity on its equator ? The radius of earth is 6.4xx10^(6) m and its ngular speed is 7.27xx10^(-5)rad//s .

In the previous question, let the ring have non-uniformly distributed charge, and let it be spinning about its axis. Let F be the net force on the ring and tau be the torque on the ring due to the straight conductor

About which axis would the moment of inertia of a body be minimum ?

The rotation of earth about its axis is

A ring of radius R has uniformly distributed charge. It spins about its axis with an angular velocity omega . P is a point on its axis at a distance x from its centre. The velocity of light in vecuum is c. The ratio of the magnetic field to the electric field at P is proportional to

Imagine an astronaut inside a satellite going around the earth in a circular orbit at a speed of sqrt((gR)/(2)) where R is radius of the earth and g is acceleration due to gravity on the surface of the earth. What is weight experienced by the astronaut inside the satellite? Assume that an alien demon stops the satellite and holds it at rest. What is eight experienced by the astronaut now? The demon now releases the satellite (from rest). What is weight experienced by the astronaut now?

The moment of inertia of a soild sphere about a tangent is (5)/(3)mr^(2) . What would be its moment of inertia about its diameter.
