Q. Electric field outside a charged cylinder depends on

आवेशित सिलेंडर के बाहर विद्युत क्षेत्र निर्भर करता है

A
Radius
त्रिज्या
B
Length
लंबाई
C
Distance from axis
अक्ष से दूरी
D
Thickness
मोटाई

Explanation

For a long uniformly charged cylinder, the electric field at a distance
r from the axis is:

E=λ2πε0rE = \frac{\lambda}{2\pi\varepsilon_0 r}

Here, λ\lambda is linear charge density. So, it inversely depends on distance from the axis, not on length, radius, or thickness of the cylinder.
