Answer:
There are 3.34 C of charge are needed to spark.
Explanation:
Given that,
Electric field, [tex]E=3\times 10^{16}\ N/C[/tex]
If the charged particles in the field are separated by a distance of 1 mm, d = 1 mm
The electric field is given by the formula as follows :
[tex]E=\dfrac{kq}{d^2}[/tex]
q is charge
[tex]q=\dfrac{Ed^2}{k}\\\\q=\dfrac{3\times 10^{16}\times (1\times 10^{-3})^2}{9\times 10^9}\\\\q=3.34\ C[/tex]
So, there are 3.34 C of charge are needed to spark.
