Transcribed Image Text:Two charges Q1= 19 µC and Q2= 4 µC are placed on the two corners of a square as shown in the figure below. If the side length of the square is a=70 mm, how
much work is required to bring a third charge, Q3= 3 µC from infinitely far away to the empty bottom-right corner of the square?
Please take k = 9.0 x 10° N.m2/c2 and express your answer using one decimal place in units of J or N.m. Please do not forget to type the minus sign if you got a
