Please help me solve these three physics questions and PLEASE SHOW WORK :) Have a great day

Electric Forces First Name: Last Name: You have three charged insulating plates (A, B and C) and one electrically neutral conducting plate (D). The diagram illustrates forces between three sets of those plates Do not concern yourself with the magnitudes of these forces. You should only focus on the directions. You will be determining the forces in the other two scenarios. A A A B B B C D C D 1. Is the force between plates B and C attractive or repulsive or is there no force? Explain your reasoning.Electric Forces 3. Three charges are fixed in place at the corners of an equilateral triangle as shown. The electric forces on each charge due to the other two charges are drawn to scale. Assume that Q1 > 0. A. Determine and explain the sign of each of Q2 the other two charges. Q1 Q3 B. Rank the magnitude of the three charges. Explain your reasoning.2. Is the force between plates B and D attractive or repulsive or is there no force? Explain your reasoning
