Answer:

The electric flux is zero because charge is zero.

Explanation:

Given that,

Positive charge $q_{1}=3.90\times10^{-12}\ C$

Negative charge $q_{2}=-2.60\times10^{-12}\ C$

We need to calculate the total charged

Using formula of charge

$Q_{enc}=2q_{1}+3q_{2}$

Put the value into the formula

$Q_{enc}=2\times3.90\times10^{-12}+3\times(-2.60\times10^{-12})$

$Q_{enc}=0$

We need to calculate the electric flux

Using formula of electric flux

$\phi=\dfrac{Q_{enc}}{\epsilon_{0}}$

Put the value into the formula

$\phi=\dfrac{0}{8.85\times10^{-12}}$

Hence, The electric flux is zero because charge is zero.

Sidana [21]

Answer with Explanation:

We are given that

$n_g=1.55$

$n_f=1.35$

$\lambda=521 nm=521\times 10^{-9} m$

$1 nm=10^{-9} m$

a.We have to find the expression for the minimum thickness the film can have ,t.

Condition for destructive interference

$2nt=(m+\frac{1}{2})\lambda$

$t=\frac{(m+\frac{1}{2})\lambda}{2n}$

For minimum thickness m=0

Then, $t=\frac{\lambda}{4n}$

b.Substitute the values

$t=\frac{521\times 10^{-9}}{4\times 1.35}=96.5nm$
