Question

find the gravitational force between man of mass 60 kg and the earth
​

Answer 1

Answer:

Calculate the gravitational force of earth acting on your friend of mass 60 kg given mass of earth is equal to 6×10^24 oh and radius of earth = 6.4×10^6m G =6.7 ×10 ^-11 Nm^2kg^-2.

Explanation:

Answer 2

The gravitational force between man of mass 60 kg and the earth is 586.23 N.

Given :

Mass of man = 60kg

To find :

The gravitational force between man and the earth

Solution :

We know ,

F = G m1m2 / R^2

• where F is the force of attraction between the man and the earth
• m1 is the mass of the man and m2 is the mass of the earth
• and R is the distance between the man and the earth

Mass of man (m1) = 60kg

Mass of Earth (m2)= 6 × 10^24 kg

R = 6.4 × 10^6 metres

G = 6.67 × 10^(-11)

Putting the values in the equation,

F = (6.67 × 10^(-11) × 60 × 6 × 10^24 ) / (6.4× 10^6)^2

= (6.67 × 10^(-11) × 360 × 10^24 ) / (6.4 × 6.4 × 10^12)

= 586.23 N

Hence, the gravitational force between man of mass 60 kg and the earth is 586.23 N.
