Question

Relative permittivity of a material is 10. It's absolute or actual permittivity is
A) 8.85x10-12 F/m
C) 9*10° F/m
B) 8.85*10-11 F/m
D) 10 F/m
​

Answer 1

Answer:

(A)8.85x10-12F/m

Explanation:

Relative permittivity is constant for a particular medium. For air or free space, it is unity. Absolute permittivity does not depend on the medium, its value is always constant=8.85*10-12F/m. Actual permittivity is the product of relative permittivity and absolute permittivity

Answer 2

Answer:

B is the correct answer

10×8.85×10^-12=8.85×10^-11
