=========================================
♦ Given,
Acceleration due to gravity (g) = 9.8 m/s
Radius of Earth (r) = 6.37 × 10^6 m
Gravitational constant (G) = 6.67/10^11 = 6.67 × 10^-11 kgm/s
♦ To find,
Mass of Earth (M)
♦ Now, we know that,
g = GM/r²
=>> gr² = GM
=> gr²/G = M
• Putting the values -
• Using identity : a^m × a^n = a^m+n,
• Using identity : 1/a^-m = a^m,
= 5.96 × 10^24 kg
♥ •°• The mass of Earth is about 5.96 × 10²⁴ kg.
