Solution:
Given that,
A jar of mass 2.1 kg sits on a table
To find: normal force acting on the jar
The table is level and there are no other forces on the book, so the normal force is equal to the mass multiplied by acceleration due to gravity
[tex]Force = m \times a[/tex]
Where,
m is mass
a is acceleration due to gravity
From given,
[tex]m = 2.1\ kg\\\\a = 9.8\ m/s^2[/tex]
Substituting the values we get,
[tex]F = 2.1 \times 9.8\\\\F = 20.58\\\\F \approx 20.6[/tex]
Thus normal force acting on the jar is 20.6 N
