As we have learnt

 

Charged Cylinder if P lies outside -

If Point P lies outside the cylinder

E_{out}=\frac{\lambda }{2\pi \varepsilon _{0}r}

V_{out}=\frac{-\lambda }{2\pi \varepsilon _{0}}\log_{e}r+c

- wherein

 

 For conducting and non conducting both when r > R

E = \frac{\lambda}{2\pi\epsilon_0r}

 


Option 1)

\frac{\lambda}{2\pi\epsilon_0 R}

Option 2)

\frac{\lambda}{2\pi\epsilon_0 }\log_e r + c

Option 3)

0

Option 4)

\frac{\lambda}{2\pi\epsilon_0 r}
