A Nonuniform Electric Field Is Directed Along the X-Axis at All

question 41

Multiple Choice

A nonuniform electric field is directed along the x-axis at all points in space.This magnitude of the field varies with x,but not with respect to y or z.The axis of a cylindrical surface,0.80 m long and 0.20 m in diameter,is aligned parallel to the x-axis,as shown in the figure.The electric fields E₁ and E₂,at the ends of the cylindrical surface,have magnitudes of 9000 N/C and 5000 N/C respectively,and are directed as shown.(ε₀ = 8.85 × 10^-12 C²/N • m²) The charge enclosed by the cylindrical surface is closest to

• A) -1.1 nC.
• B) 1.1 nC.
• C) -2.4 nC.
• D) -4.8 nC.
• E) 4.8 nC.
