I need help with this:

Question 1 Not yet Two charges. Q1 = 8.60 /C, and Q2 = -2.44 JC are separated by distance d = 4.22 cm. Q1 is at (x, y) = (0, 0) and Q2 is at (z, y) = (0, d). Part 1) Marked out of If a third charge Q3 = 6.51 /C is placed at (z, y) = (d, 0). what is the magnitude of the force on Q3? 1.00 FQal question Part 2) What is the electric field at (x, y) = (d, d) due to all three charges? E = 3N/C Part 3) An electric dipole consisting of charges Q1 = 8.60 /C and -Q1 = -8.60 /C separated by distance of s = 7.22 um is placed in a uniform electric field E = 67.5i N/C. How much work needs to be done to turn the dipole from 0; = 33.90 to 0, = 83.40 where 0 is the angle between the electric dipole moment and the electric field? W = Next page
