QUESTION:
Currently, the moon goes around the earth once every 27.3 days. If the moon could be brought into a new circular orbit with a smaller radius, its orbital period would be A. More than 27.3 days. B. 27.3 days. C. Less than 27.3 days.
ANSWER:Solution 28MCQ Step 1 of 2 The time period in the given orbit is the time taken by the satellite to complete one full revolution. The relation between the orbital time period T and the radius of the orbit in which satellite is been revolving is given by, 2 3 T = 4 r GM Where T is the orbital time period, r is the radius of the orbit, G is gravitational constant and M is the mass.
