Answer:

Answer:

Step-by-step explanation:

F = Force of attraction between two objects (N)

G = universal gravitational constant = 6.67259 x 10–11 N m2/kg2.  

m1,m1 = two different masses (Kg)

r = is the distance between them

Solved Numericals

Example 1

Determine the gravitational force if two masses are 30kg and 50kg separated by a distance 4m.

G = 6.67259 x 10–11 N m2/kg2.  

Solution:

Given:

m1 = 30 kg, m2 = 50 kg

r = 4m and

G = 6.67259 x 10–11 N m2/kg2.  

Universal gravitation formula is given by,

Universal Gravitation Formula

 = [6.673×10–11 ×30×50] / 16

F = 62.55 x 10–11N

Example 2

Determine the gravitational force if the mass of two bodies are 80 kg and 200 kg and they are separated by a distance of 6m.

Solution:

Given:

m1 = 80 kg, m2 = 100 kg,

r = 6m and

G = 6.67259 x 10–11 N m2/kg2.

Universal gravitation formula is given by,

F=Gm1m2 / r2

=6.673×10–11× 80×100 / 36

F =148.28×10–11N

Verified answer

Answer:

Determine the gravitational force if two masses are 30kg and 50kg separated by a distance 4m. G = 6.67259 x 10–11 N m2/kg2. G = 6.67259 x 10–11 N m2/kg2
