Expert Solution
Step 1
Given data:
The charge per unit length of filament is: λ = -90.6μC/m
The electric field is: E
Let us consider the filament as a cylinder.
(1)The expression for an electric field by using Gauss law is given as,
Here, εo is the free space permittivity = 8.85 ×10-12 F/m.
Put all known values in the above expression and calculate the value of the electric field at r = 10 cm = 0.1m.
Thus, the value of electric field at r = 10 cm = 0.10 m is -16.32 MN/C.
