Option (1)

Explanation:

Given tha the length of the cylindrical shaped artificial sattelite is 20 m and it is rotating about an axis which is perpendicilar bisector of the axial length (20m) of the satellite.So the radius of rotation is # r=10m#. If w is the angular velocity of rotation then the centrifugal acceleration produced due to this rotation will creat artificial gravity #4.9m/s^2#

So we can write

#"Centrifugal acceleration "=w^2*r=4.9#

#=>w^2*10=4.9=>w^2=0.49=>w=0.7#

#2pixxn=0.7#,where n = frequency of rotation

#:.n=0.7/(2*pi)~~0.1Hz#
