Question

Calculate Fg = (6.67×10^-11Nm^2/kg^2) (6×10^24 kg) (60kg)/6400 km​

Answer 1

Answer:

Given ⤵

➡$\frac{ 6.67 \times {10}^{ - 11} \times 6 \times {10}^{24} \times 60 ) }{( {6400 \times 1000)}^{2} }$

To find ⤵

➡$F_g$

Solution⤵

6400km converting into m=6400×1000m

$\frac{6.67 \times 6 \times 60 \times {10}^{24 - 10}}{40960000 \times 1000000} \\= \frac{6.67 \times 6 \times 60 \times {10}^{13} }{4.096 \times {10}^{13} } \\= \frac{6.67 \times 6 \times 60 \times {10}^{13 - 13} }{4.096} \\ = \frac{6.67 \times 6 \times 60}{4.096} \\ = \frac{2401.2}{4.096} \\ =586.23$

Hence $F_g$=586.23m/s².
