Question

3. What is the electric flux through a sphere that has radius of 0.5 m and carries 100 uC of charge at its center? A hollow metal sphere with radius 0.45 m carries a net charge of 0.25 nC. Find the magnitude of the electric field, 4. (a) At a point 0.1 m outside the surface of the sphere (b) At a point 0.1 m inside the surface of the sphere 5. An infinitely long line of charge carries a linear charge density of 4.8 HC/m. Find the electric field at a distance of 0.2 m from the line of charge along the x-direction?

Explanation / Answer

here,

3)

radius , r = 0.5 m

charge , Q = 100 uC = 1 * 10^-4 C

the electric flux through the sphere , phi = Q/e0

phi = 1 * 10^-4 /( 8.85 * 10^-12) N/C.m^2

phi = 1.13 * 10^7 N/C.m^2

the electric flux through the sphere is 1.13 * 10^7 N/C.m^2
