Question

answer me 9th no. question​

Answer 1

F = GMm/R^2

where,

G is gravitational constant

= 6.67×10^-11 kg m/s^2

M is mass of earth

= 6×10^24 Kg

m is mass of the object

= 1 kg

R is radius of the earth

= 6.4×10^6 m

F = GMm/R^2

= 6.67×10^-11×6×10^24×1/(6.4×10^6)^2

= 6.67×6×10^(-11+24)/(6.4×10^6) (6.4×10^6)

= 40.02×10^13/40.96×10^12 kg m/s^2
