Explanation / Answer
gravitational force between the object of mass m and jupiter = gravitational force between the object of mass m and Sun
G*Mj*m/x^2 = G*Ms*m/(6.99*10^7 - x)^2
Mj = 1.9*10^27 Kg
Ms = 1.991*10^30 Kg
1.9*10^27/x^2 = (1.991*10^30)/(6.99*10^7 - x)^2
(6.99*10^7 - x)^2 / x^2 = (1.991*10^30)/ (1.9*10^27) = 1047.9
(6.99*10^7/x ) - 1 = sqrt(1047.9) = 32.37
6.99*10^7/x = 1+32.37 = 33.37
x = (6.99*10^7)/33.37 = 2.09*10^6 m From the Jupiter
