Answer:
Explanation:
The gravitational force is an attractive force exerted between any objects with mass.
The magnitude of the gravitational force between two objects is given by:
where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between the two objects
In this problem, we have:
is the mass of the 1st ball
is the mass of the 2nd ball
r = 5 m is the separation
So, the gravitational force between them is
Answer: 98 N
Explanation:
The weight of an object is given by
where m is the mass of the object, and g is the gravitational acceleration.
In this problem, m=10 kg is the mass of the lemur, while the gravitational acceleration is . Therefore, the weight of the lemur is
