Question 1:

A d B d a) Find the potential due to the three charges A = 6 /C. B = 6 /C and C = -6 /C at the lower left corner (d = 5.5 cm): b) A charge -3 AC is placed at the lower left corner. What is its potential energy? c) What is the potential energy of the system of four charges?q: in I: [13 Three point charges q1 = 'i'pC. {12 = auto and 133 are located as shown in the figure above-J where a = 4cm. 3.: = 2.75331 and c. = 2.9 om.
