(a) Complete the function definition in the code cell below for a function called efield_rod which has the linear charge density, the location where the electric field is calculated, the length of the rod and the number of line segments as input variables. Output is the electric field of a rod. [6 marks) (b) Check that you get the same result from your function as you got above.
