A. 4.78*10-11 C2N-1m-2
B. 8.85*10-10C2N-1m-2
C. 4.5*10-10C2N-1m-2
D. 3.2*10-11C2N-1m-2
Answer:A
What will be permittivity of a medium which has dielectric constant 5.4?
A. 4.78*10-11 C2N-1m-2 B. 8.85*10-10C2N-1m-2 C. 4.5*10-10C2N-1m-2 D. 3.2*10-11C2N-1m-2
Explanation: ?o=8.854*10-12C2N-1m-2. Therefore the permittivity will be 5.4*8.854*10-12C2N-1m-2 = 4.78*10-11C2N-1m-2. We know that permittivity of a medium is equal to its relative permittivity multiplied to the absolute permittivity of air. Air has relative permittivity =1.
