The acceleration of a different speck of dust is 40 m/s.
Since the radius is been given as double and angular velocity will be constant, we can calculate the centripetal acceleration as
a = (2r)ω²
If we substitute the given values of r= 2r , and ω²= 20m/s.
Then we have
Therefore, acceleration of a different speck of dust is 40 m/s.
