Solve each part of given question:
Question: Three point charges are arranged in a horizontal line as shown below. Find the electric force on Q1 given the following: Q1 = -4 mC, Q2 = -5 mC, Q3 = 3 mC, r1 = 80 m, and r2 = 160 m. Remember that a positive force points to the right and a negative force points to the left.
Part A: What is the net force on charge Q1?
Part B: What is the net force on charge Q2?
Part C: What is the net force on charge Q3?
Part D: What is the sum of the forces on all three charges?
Having trouble with this physics question, can you please explain with the answer.
