Correction Exercice 2

$F = G \frac {m_A \times m_B} {d^2} = 6,67 \times 10^{-11} \times \frac {6,0 \times 10^{24} \times 2,0 \times 10^{30}} {(150 \times 10^9)^2} = 3,6 \times 10^{22} N$

$F = G \frac {m_A \times m_B} {d^2} = 6,67 \times 10^{-11} \times \frac {6,0 \times 10^{24} \times 7,342 \times 10^{22}} {384000000^2} = 2,0 \times 10^{20} N$

m_trousse = 200g = 0,2 kg

$F = G \frac {m_A \times m_B} {d^2} = 6,67 \times 10^{-11} \times \frac {6,0 \times 10^{24} \times 0,2} {(6400000)^2} = 2 N$

m_stylo = 5g = 0,005 kg

$F = G \frac {m_A \times m_B} {d^2} = 6,67 \times 10^{-11} \times \frac {0,005 \times 0,005} {(0,1)^2} = 1,7 \times 10^{-13} N$
