The physics problem is described in the picture

Three point charges Q1 = -2.2 uC, Q2 = -3.2 uC and Q3 = -0.6 uC are initially, infinitely far apart. They are then brought together and placed at the corners of an equilateral triangle. Each side has a length of 41 cm. Determine the total electric potential energy of these group of charges. Express your answer in mJ.   show complete solution  and express the answer in 4 decimal places if posssible

As stated in the pic

An electron moving parallel to the x axis has an initial speed of 5.06 x 10° m/s at the origin. Its speed is reduced to 1.28 x 105 m/s at the point x = 2.00 cm. %3D (a) Calculate the electric potential difference between the origin and that point. Volts (b) Which point is at the higher potential? both have the same potential the point x = 2.00 cm the origin
