Assertion The dielectric constant is a number without dimensions. Reason Dielectric constant is a ratio.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Dielectric constant is the ratio of a material's permittivity to vacuum permittivity, making it a dimensionless number. The reason correctly explains why it has no dimensions.
