The correct answer is: D. no units<\/p>\n
Relative permittivity is a dimensionless quantity that is used to compare the permittivity of a material to the permittivity of a vacuum. It is denoted by the Greek letter $\\epsilon_r$. The permittivity of a vacuum is a fundamental constant of nature, and it is denoted by the Greek letter $\\epsilon_0$. The permittivity of a material is given by the equation:<\/p>\n
$$\\epsilon = \\epsilon_r \\epsilon_0$$<\/p>\n
Therefore, the relative permittivity is a dimensionless quantity.<\/p>\n
Option A is incorrect because the units of farad per meter (F\/m) are the units of permittivity.<\/p>\n
Option B is incorrect because the units of meter per farad (m\/F) are the units of inverse permittivity.<\/p>\n
Option C is incorrect because the units of weber per meter (Wb\/m) are the units of magnetic flux density.<\/p>\n","protected":false},"excerpt":{"rendered":"
