(a) pi/2 rad/hr

(b) pi/3 rad/hr

(c) pi/6 rad/hr

(d) pi/12 rad/hr

I had been asked this question in class test.

I want to ask this question from Gravitation in portion Gravitation of Physics – Class 11

Best answer
Right choice is (d) pi/12 rad/hr

The best I can explain: Parking satellites (or) geostationary satellites have a time period of 24 hours. This means that it takes 24 hours to complete 1 revolution, i.e., 2*pi radians.

Therefore; angular velocity = (2 x pi)/24 rad/hr

 = pi/12 rad/hr.
