Pertanyaan

Planet Mars dan Bumi memiliki jarak 6779 km. Jika diketahui massa bumi 5 cross times 10 to the power of 31 space kg dan massa planet Mars 2 cross times 10 to the power of 20 space kg, tentukan besar gaya gravitasinya! space

Pembahasan Soal:

Diketahui.
r space equals space 6779 space km space equals space 6779 space cross times 10 cubed space straight m equals 6 comma 779 space cross times 10 to the power of 6 space straight m M subscript b u m i end subscript equals space 5 cross times 10 to the power of 31 kg M subscript m a r s end subscript equals space 2 cross times 10 to the power of 20 space kg space G space equals space 6 comma 67 space cross times 10 to the power of negative 11 end exponent space straight N space left parenthesis straight m divided by kg right parenthesis squared

Maka Gaya gravitasinya adalah.

table attributes columnalign right center left columnspacing 0px end attributes row cell F subscript g end cell equals cell space fraction numerator G M subscript 1 M subscript 2 over denominator r squared end fraction end cell row blank equals cell space fraction numerator 6 comma 67 space cross times 10 to the power of negative 11 end exponent space left parenthesis space 5 cross times 10 to the power of 31 right parenthesis left parenthesis 2 cross times 10 to the power of 20 right parenthesis over denominator left parenthesis 6 comma 779 space cross times 10 to the power of 6 right parenthesis squared end fraction end cell row blank equals cell space fraction numerator 66 comma 7 space cross times 10 to the power of 40 over denominator 45 comma 95 space cross times 10 to the power of 12 end fraction end cell row blank equals cell space 1 comma 45 space cross times 10 to the power of 28 space end exponent straight N end cell end table

Oleh karena itu, jawabannya adalah bold 1 bold comma bold 48 bold space bold cross times bold 10 to the power of bold 28 bold space bold Nspace
