N-mWhat quantity f ye The electric flux through a closed surface is found to be 2.5 m 4. 5. A closed surface encloses a net charge of 5.5x10° C. What is the net lcni fl tre -6

Answer 1

4.

$\phi$ = electric flux through a closed surface = 2.5 Nm²/C

Q = charge enclosed within closed surface = ?

Using gauss's law

$\phi$ = Q/ $\epsilon _{o}$

inserting the values

2.5 = Q/(8.85 x 10^-12)

Q = 2.2 x 10^-11 C

5.

$\phi$ = net electric flux through the surface

Q = net charge enclosed within closed surface = 5.5 x 10^-6 C

Using gauss's law

$\phi$ = Q/ $\epsilon _{o}$

inserting the values

$\phi$ = (5.5 x 10^-6)/(8.85 x 10^-12)

$\phi$ = 6.2 x 10⁵ Nm²/C
