The electric field between two parallel plates of a capacitor is 2.1 × 10 –5 . If a medium is inserted between the plates than the electric field becomes 1.0 × 10 –5 . Now, the value of dielectric will be
Text Solution
Verified by ExpertsThe correct answer is:
A
E = 
= 2.1 × 10 –5
E’ = 
= 1 × 10 –5
∴ 
or K = 2.1 ≈ 2
