Can someone help, I really don't understand how to do these

Given the charge values and the distances, determine the electrostatic force between the charged particles and if they are attracted, repelled, or neither. Charge 1 Charge 2 Distance Apart Force Attracted / Repelled / Neither Trial 1 -2 LLC 8 LLC 4 cm Trial 2 -4 JC 8 LLC 4 cm Trial 3 -6 LLC 8 LLC 4 cm Trial 4 -8 JC 8 LLC 4 cm Column A Column B 1. Trial 1: Force = a. -719.004 N 2. Trial 2: Force = b. - 44.938 N 3. Trial 3: Force = C. 89.876N Trial 4: Force = d. 44.938 N 5 Trial 1: Are the two charge ions attracted, e. -179.751 N repelled, or neither?
