Explanation / Answer

Ans:-

Given data:-x1= 1.5*10^5m, x2 = 8.5*10^5m

m1=3.5*10^3kg, m2= 8.5*10^15kg

Part a] d= x2 – x1

= 8.5*10^5 – 1.5*10^5                                                                                                                                                                 

d= 7*10^5m = 700000m

Part b]Gravitational force F= G m1 m2 / R^2

F = 6.67*10^-11m^3/kg.s^2*3.5*10^3 * 8.5*10^15 / (7*10^5)^2

F= 4.05*10^-3N

Part c] Fnet = P /t

P = Fnet *t

= 4.05*10^-3 * 4.5

P = 0.018kg m/s
