Answer:
The electric flux is zero because charge is zero.
Explanation:
Given that,
Positive charge [tex]q_{1}=3.90\times10^{-12}\ C[/tex]
Negative charge [tex]q_{2}=-2.60\times10^{-12}\ C[/tex]
We need to calculate the total charged
Using formula of charge
[tex]Q_{enc}=2q_{1}+3q_{2}[/tex]
Put the value into the formula
[tex]Q_{enc}=2\times3.90\times10^{-12}+3\times(-2.60\times10^{-12})[/tex]
[tex]Q_{enc}=0[/tex]
We need to calculate the electric flux
Using formula of electric flux
[tex]\phi=\dfrac{Q_{enc}}{\epsilon_{0}}[/tex]
Put the value into the formula
[tex]\phi=\dfrac{0}{8.85\times10^{-12}}[/tex]
Hence, The electric flux is zero because charge is zero.
