Dear Student,

electric field around the charged cylinder E=λ2πε0rwhere lamda is the linear charge density which is a constant 
hence option A is correct from the above eqn Regards

4) Intensity of electric field at a point close and outside a charged conducting cylinder is proportional to : (r is the distance of a point from the axis of cylinder). ( a ) 1 r ( b ) 1 r 2 ( c ) 1 r 3 ( d ) r 3

4) Intensity of electric field at a point close and outside a charged conducting cylinder is proportional to : (r is the distance of a point from the axis of cylinder).
$(a) \frac{1}{r} (b) \frac{1}{r^{2}} (c) \frac{1}{r^{3}} (d) r^{3}$
