Q1) A satellite weighing ( 700 Ib ) on the surface of the Earth. Calculate the Earth's gravitational force for this satellite when it is positioned at a distance of ( 36000 km ) from the surface of the Earth, where its rotation speed around the Earth is equal to the speed of the Earth's rotation around itself. - Earth mass ( Me ) = 5.97 × 102ª kg. - Radius of the Earth ( Re ) = 6371 km. 36000 km
1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?
