Question

A capacitor filled partially with dielectric material of dielectric constant 'k'. Its electric potential versus position graph is as shown. The distance between the two plates is 4 mm. The dielectric constant of the medium is ______.

 

Options

• 1.00

• 2.00

• 3.00

• 4.00

Answer 1

A capacitor filled partially with dielectric material of dielectric constant 'k'. Its electric potential versus position graph is as shown. The distance between the two plates is 4 mm. The dielectric constant of the medium is 3.00.

Explanation:

`(10 - 4)/(2 - 0) = k(4 - 3)/(3 - 2)` ⇒ k = 3
