Question

The unit of absolute permittivity is

• A. Farad – meter
• B. Farad / meter
• C. Farad/meter ²
• D. Farad

Answer 1

Answer: (B)

Farad / meter

Answer 2

From the formula $C = 4\pi\varepsilon_{0}R$ $\therefore$ $\varepsilon_{0} = \frac{C}{4\pi R}$

By substituting the unit of capacitance and radius : unit of $\varepsilon_{0} =$ Farad/ meter
