Question

Relative permittivity and permeability of a material are  `epsilon_"r"` and `µ_"r"` respectively. Which of the following values of these quantities are allowed for a diamagnetic material?

पर्याय

• `epsilon_"r" = 1.5,`  `µ_"r" = 0.5`

• `epsilon_"r" = 0.5,`  `µ_"r" = 0.5`

• `epsilon_"r" = 1.5,`  `µ_"r" = 1.5`

• `epsilon_"r" = 0.5,`  `µ_"r" = 1.5`

Answer 1

`epsilon_"r" = 1.5,`  `µ_"r" = 0.5`

Explanation:

`µ_"r" < 1` and `epsilon_"r" > 1`
