Explanation:
It is given that,
Radius of circular orbit,![r=3.99\times 10^{11}\ m](/tpl/images/0188/8416/c188b.png)
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.
