Answer:
<h3>C. 6.50 x 10^3</h3>
Explanation:
The satellite revolves around moon due to centripetal force which is provided by gravity in this context so we can equate gravity and centripetal force.

where, m is mass of satellite
M is mass of moon
ω is angular velocity
G is Universal gravitational constant
R is the radius of moon
from the above equation we get ω as,



here M = 7.36 X 10^22
R = 1.738 X 10^6
G =6.67 X 10^-11

T= 6.50 X 10^3 seconds
