Answer:
here is ur answer bro
Given : λ = 2 × 10–6c/m For the previous problem. E = λ/∈02πr for a cylindrical electricfield. Now, For experienced by the electron due to the electric filed in wire = centripetal force. = 2.88 × 10–17J.Read more on Sarthaks.com - https://www.sarthaks.com/64423/a-long-cylindrical-wire-carries-a-positive-charge-of-linear-density-2-0-x-10-8c-m
