d) Two charges Q1 and Q2 are held stationary 1 m away from each  other. The magnitude of charge of Q2 is twice that of Q1. A positive  point charge A is placed directly in the middle of the two charges  (Q1 and Q2). What is the ratio of the net force on charge A when  Q1 and Q2 are both negative over the net force on charge A  when Q1 is negative and Q2 is positive?

Question

d) Two charges Q1 and Q2 are held stationary 1 m away from each 
other. The magnitude of charge of Q2 is twice that of Q1. A positive 
point charge A is placed directly in the middle of the two charges 
(Q1 and Q2). What is the ratio of the net force on charge A when 
Q1 and Q2 are both negative over the net force on charge A 
when Q1 is negative and Q2 is positive?

b) Choose a path around this point charge and calculate the line integral fjE.dl.
compare with the coulomb result.
