A
YES
2
Q
What does epsilon denote?
A
Permittivity of medium
3
Q
What does epsilon0(not) denote?
A
Permittivity of free space
4
Q
Relations between force and permittivity?
A
Directly proportional
5
Q
What is permittivity?
A
It permits its own field to decrease interaction field between charges
6
Q
When is the value of epsilon minimum?
A
In vacuum/free space/air
7
Q
State True or False.
Force in any medium is less than that in air
A
True
8
Q
What is relative permittivity?
A
Relative permittivity = Permittivity of medium
—————————
Permittivity of air
