Explanation:
It is given that,
Radius of circular orbit, 
Time taken,
(a) Angular speed of the planet is given by :


(b) The tangential speed of the planet is given by :


v = 110124 m/s
(c) The centripetal acceleration of the planet,



Hence, this is the required solution.
Answer:
A
Explanation:
Force = mass x acceleration
if the force is constant for each of the boxes, the smaller a boxes mass the greater its acceleration while the force is applied
Therefore the smaller box will have a greater initial velocity and will slide the furthest before it stops.
