I need step by step solutions, they need to be clear so I understand what are the steps taken.

Problem 1 On the right you can see the field map for an arrangement of three point charges. One of the particles has charge (; and the other two have charge Q2, as shown. (a)What is the ratio of |Q1| to |Qal? (b)What are the signs of Q1 and Q2? Problem 2 One of the rules for drawing correct field maps is that you should never have electric field lines crossing anywhere Why. physically, is that? (Think back on the definition of a field line.) Problem 3 The picture shows two "infinite" lines of charge The one on the left runs vertically, parallel to the y axes, the one on the line line right is parallel to the 2 axis, so you are looking at it head on charge 1 charge 2 Both of them have the same linear charge density. A -3010/m. The distance d that shows in various places in the figure equals d = 4.Dem. (a ) Calculate the electric field at the point , and report it as a vector. (b) Draw the electric field vectors of both lines of charge at d/2 point P. and the resultant electric field vector (c) Draw the direction of the force that the ( total ) field would exert on a negative charge placed at point ]" d - Problem 4 The figure on the right shows an electric dipole in the electric field of a point charge +Q (a)Draw the direction of the electric force on the posi- tive and negative charges that make up the dipole (b)Indicate the direction of rotation of the dipole. (c)Draw the approximate direction of the initial motion of the center of the dipole
