I am taking grade 12 physics I don't want it too complicated and possibly written in google docs or something similar i don't understand the fancy handwriting too much

Two charges q, = -25 C and q; = 4.0 C are placed 0.012 m apart. A third negative charge q2 is placed a distance L from 9 1 as shown. If the net electric force on 92 is 0 N, what is the value of L? (A:4, C:2) 91 42 X TAn electron gun has a uniform electric field of 425 N/C. An electron starts from rest and is fired from the gun, reaching a speed of 3.25 x 10' m/s. How far does the electron move relative to the field? (A:3, C:2)An alpha particle with a charge of 2e is fixed at the origin. A proton is aimed at the alpha particle, and shot at it from a distance of 2.00 m at a speed of 3.04 x 10 m/s. How close will the proton come to the alpha particle before coming to a stop? (A 3, C:2)Six point charges each with charge of = 81.0 AC are arranged on the vertices of a hexagon that has a side length of 15.2 cm. What is the electric potential due to the six charges at the centre of the hexagon? (T: 5, C:2) 15.2 cm
