(slightly different than the first question I asked) We have an infinitely long line charge of negative linear charge density λ=−5nC/m. We also have an electron that is initially r= 10m away from the line charge, and it is moving directly towards the line charge at an initial speed of v0= 10 7m/s. Given that the electric field of an infinitely long line charge is E=(2kλ)/r, calculate how close the electron gets to the line charge. (Hint: You will need to do an integral.)
