Question

calculate the force of Gravitation due to Earth on a ball of 1kg mass lying on the ground.(then mass of the Earth=6×10²⁴ kg, radius of Earth equal to 6.4×10⁶m, G=6.7×10-¹¹Nm²Kg-²)​

plz give the correct answer

Answer 1

Answer:

According to Newton's Law

F = (G*m1*m2)/r^2

Explanation:

here G = 6.7 × 10-¹¹ Nmkg-²

m1 = 1 kg kg

m2 = mass of earth = 6 × 10 ²⁴ kg

r = radius of earth = 6.4 × 10^6 m

so, F = 6.7 × 10-¹¹ × 1 × 6 × 10^24 / ( 6.4 × 10^ 6)²

therefore F = 9.81 N
