Question

................plz help

Answer 1

here mass of the earth is , M = 6 × 10^24 kg

mass of the satellite, m = 1000kg

distance , r = 20000km = 2 × 10^7 m

hence we know

force F = (GMm) / (R^2)

= [ (6.67 × 10^-11 ) × (6 × 10^24) × (1000)] ÷ [2 × 2 × 10^14]


=10.005 × 10^2


= 1000.5 N
= 1000 N


hope it helps

have a great day
