We know that electric potential = summation kq/r
= 9e9*31e-6/0.38 + 9e9*-41e-6/[0.38* sqrt 2] + 9e9*31e-6/0.38 + 9e9*-40e-6/[ 0.38/ sqrt 2]
= -557998 V answer

Function 1:
Write a function that accepts an integer argument and returns
the sum of all the integers from 1 up to the number passed as an
argument. For example, if 50 is passed as an argument, the function
will return the sum of 1, 2, 3, 4, ... 50. Use recursion to
calculate the sum. Demonstrate the function in a
program.
