MCQ
Units of electric flux are
- A$\frac{{N - {m^2}}}{{Cou{l^2}}}$
- B$\frac{N}{{Cou{l^2} - {m^2}}}$
- ✓$volt-m$
- D$Volt-m^3$
✓
Answer
Correct option: C.
$volt-m$
c
Electric flux $=$ electric field $\times$ area $=| dV / dx | \times m ^2= V / m \times m ^2= V . m$
Electric flux $=$ electric field $\times$ area $=| dV / dx | \times m ^2= V / m \times m ^2= V . m$
or Electric flux $=$ electric field $\times$ area $=F / q \times A = N / C \times m ^2=\frac{ N \cdot m ^2}{ C }$
