Two identical point charges (q = +1.00 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.420 m. A test charge (90 = -7.50 × 10-8 C), with a mass of 2.80 x 10-8 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square. Number i Units .90 VB

Two charges Q1= -48 µC and Q2= -21 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=48 mm, how much work is required to bring a third charge, Q3= -28 µC from infinitely far away to the empty bottom-right corner of the square? Please take k = 9.0 x 109 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 negative value. Q1 а а а Q2 а
