Answer:
2388078.86544 N/C
Step-by-step explanation:
= Charge density = 9.22 mC/m³
r = Distance = 7.35 cm
= Outer radius = 3.5 cm
= Inner radius = 2.98 cm
l = Length of cylinder
= Permittivity of free space =

V = Volume
E = Electric field
Charge is given by

Area

From Gauss law the flux through a cylindrical surface is given by

The electric at the given distance is 2388078.86544 N/C
