Question
please answer question number 5
4. A uniform surface charge density of 500 nC/m3 is distributed throughout a spherical volume (radius 16 cm). Consider a cubical (4.0 cm along the edge) surface completely inside the sphere. Determine the electric flux in Nm2/C for this surface. (co-8.85 x 10-12 C2/Nm 2) a. 7.1 b. 3.6 c. 12 d. 19 e. 970 5. A uniform linear charge density of 4.0 nC/m is distributed along the entire x-axis. Consider a spherical (radius 5.0 cm) surface centered on the origin. Determine the electric flux in Nm2/C for this surface. ( 8.85x102 C2/Nm2
Explanation / Answer
Q= product of linear charge density and length along x axis
Q=20nc
Electric flux=Q divided by cofficient of permittivity
Q is known,cofficient of permittivity is known apply in formula
Electric flux=22.59 Nm2/c (answer)
