Answer:

I = [tex]R^{2}[/tex](K+5)

Explanation:

Given :

J = k+5

Now selecting a thin ring in the wire of radius "r" and thickness dr.

Current through the thin ring is

dI = J X 2πrdr

dI = (K+5) x 2πrdr

Now integrating we get

I = [tex]\int_{0}^{R} = (K+5).2\pi rdr[/tex]

I = (K+5) 2π[tex]\int_{0}^{R} rdr[/tex]

I = (K+5) 2π [tex]\frac{R^{2}}{2}[/tex]

I = [tex]R^{2}[/tex](K+5)
