According to Kepler’s law the time period of a satellite varies with its radius as
Text Solution
Verified by ExpertsThe correct answer is:
C
According to Kepler’s Third Law of planetary motion, the time period of a satellite (T) is related to its orbital radius (R) by the equation:
$$ T^2 \propto R^3 $$
or, equivalently,
$$ T = k \cdot R^{3/2} $$
where k is a constant depending on the mass of the planet. This means that the time period squared is proportional to the cube of the radius.
Therefore, the correct option is option C.
