A Gaussian surface in the form of a hemisphere of radius R = 3.04 cm lies in a uniform electric field of magnitude E = 1.64 N/C.
Likurg_2 [28]

Answer:

Part a)

\phi = -4.76 \times 10^{-3} Nm^2/C

Part b)

\phi_{curved} = 4.76 \times 10^{-3} Nm^2/C

Explanation:

Part a)

Electric flux entering into the base

so it is given as

\phi = E.A

\phi = - EA

\phi = -(1.64)(\pi r^2)

\phi = -(1.64)(\pi\times 0.0304^2)

\phi = -4.76 \times 10^{-3} Nm^2/C

Part b)

Now since we know that there is no enclosed charge in the hemisphere

so net flux must be zero

\phi_{curved} + \phi_{flat} = 0

\phi_{curved} - 4.76 \times 10^{-3} = 0

\phi_{curved} = 4.76 \times 10^{-3} Nm^2/C
