Question

A body is suspended from a spring balance kept in a satellite. The reading of the spring balance is w1 when the satellite goes in an orbit of radius R and w2 when it goes in an orbit of radius 2R

Answer 1

In either cases of different radii of R and 2R, the satellite behaves like a freely falling body. So, the acceleration in either cases = acceleration due to gravity (g). The reading of the spring balance is given by the expression W = m g Hence, the acceleration due to gravity remains the same for both and the reading of the spring balance remains same as well, in both the cases.
