Imagine the standard kilogram is located on Earth's equator, where it moves in a circle of radius `6.400x10^(6)`m (Earth's radius) at a constant speed of 465m/s due to Earth's rotation. (a) What is the magnitude of the centripetal force on the standard kilogram during the rotation? Imagine that the stadard kilogram hangs from a spring balance at that location and assume that it would weigh exactly 9.80 N if Earth did not rotate. (b) What is the reading on the spring balance, that is what is the magnitude of the spring balance from the standard kilogram.
