The acceleration in a satellite orbiting around earth is
(b)
2
8
3
g
(d) zero​

Answer 1

Explanation:

Solution. a = F m = 3.0 × 10 29 N ( 800 × 10 9 ) ( 2.0 × 10 30 kg ) = 1.9 × 10 −13 m/s 2 . a = F m = 3.0 × 10 29 N ( 800 × 10 9 ) ( 2.0 × 10 30 kg ) = 1.9 × 10 −13 m/s 2 . Since the galaxies are in a circular orbit, they have centripetal acceleration.
