Answer 1

Explanation:

9.8N

hope it helps you............

Answer 2

Use the formula, F = G mM/r^2

Where, M = mass of earth = 6 × 10^24 kg

m = 1 kg

r = radius of earth = 6.4 ×10^6 m

G = 6.67 × 10^-11

Thus,

F = (6.67 × 10^-11 × 6 × 10^24 × 1)/(6.4 × 10^6)^2

= (40.02 ×10^13)/(40.96 × 10^12)

≈ 1 × 10

= 10 N

Hence the force is roughly equal to 10 N
