A satellite orbits around Planet X at the distance (from center to center) 10,00

Question

A satellite orbits around Planet X at the distance (from center to center) 10,000 km. The mass of the satellite is 100 kg.. The mass of Planet X =(1/6.67) x 1024 kg( 6 points)

7) What is the gravitational force on the satellite?                                        

8) What is the escape speed the satellite?                                                                  

9) What must be the speed of the satellite to stay in orbit period?                                     

10) M2 is situated in the middle of a line connecting the two masses (M1) as shown. The following is true about the acceleration of m2 and the net force on mass m2

a)The acceleration is zero and but the net force is NOT zero.

b) The acceleration is non zero but the net force zero

c)Both the acceleration and the net force are zero

d)It is very difficult to say because the we don
