At the surface of Mars the acceleration due to gravity is 3.8m/s . A book weighs 34 N at the surface of the earth. What is it’s
1 answer:
Answer:
On the surface of Mars:
Mass, m = 3.47 kg
Weight, W' = 13.186 N
Solution:
As per the question:
Acceleration due to gravity at the surface of Mars, g' =
Weight of book on the Earth's surface, W = 34 N
Now,
We know that:
Weight, W = mg
where
m = mass of the body
a = acceleration due to gravity on the earth's surface =
Thus the mass of the body on the surface of the earth, m:
<em>Also, we know that mass is constant and it is the weight of the body that varies with the acceleration due to gravity.</em>
Now,
Mass of the body on the surface of Mars will be same and is equal to m = 3.47 kg
Weight of the book on the surface of Mars, W' = mg'

Answer:
The gravitational force is related to the mass of each object.
The gravitational force is an attractive force.
Explanation:
Gravitational force is a long range force of attraction between any two masses.
Mathematically given as :
where:
are the masses
r= distance between the center of mass of the two objects.
G= gravitational constant =
From the above relation of eq. (1) it is clear that,
Gravitational force is inversely proportional to the square of the distance and directly proportional to the masses.
The mass of an object is independent of its size due to the fact that density may vary for different objects.
The force of gravity varies with height as:
where:
gravity at height
of the center of mass of the object from the center of mass of the earth.
and we know that force:
where: m= mass of the object.
The mathematical and proportional relationship between mL and said us that
is equivalent to 1mL.
If the density is considered as the amount of mass per unit volume we will have to
here,
m = mass
V = Volume
Replacing we have that
As we have that the density in g/mL is,
