Question

Two marbles, each with a mass of 10 g, are placed 5 m apart. What can said of the gravitational force between them?

Answer 1

Answer:

2.67*10⁻¹⁶N

Step-by-step explanation:

The gravitational force between two masses is expressed as

F=Gm₁m₂/d²

where m is the mass value,

G is the gravitational constant with a value 6.67*10⁻¹¹Nm²kg⁻² and

d is the distance between the masses

Since the masses are of equal value I.e m₁ and m₂=10g=0.01kg and distance d=5m.

If we substitute values we arrive at

F=(6. 67*10⁻¹¹ *0.01*0.01)/5²

F=2.67*10⁻¹⁶N

Hence in conclusion, the gravitational force between two masses of mass 10g at distance 5m is 2.67*10⁻¹⁶N
