Answer:
The magnitude of the electric field is 8.47 N/C
Explanation:
Given;
uniform charge density, λ = 100 nC/m³
inner radii of the cylinder, r = 1.0 mm and 3.0 mm
distance from the symmetry axis, R = 2.0 mm

Area = 2πrl
Area =2π(2 x 10⁻)l
Volume = A x d
d = Volume / Area

the magnitude of the electric field

Therefore, the magnitude of the electric field is 8.47 N/C
Answer:
a differenceis that the string needs force to be used. without something pulling on it then it wont make the noise. meanwhile the pipe only needs air to be blow Wich can be caused naturally or intentionally
