  1. both negative
  2. Upper positive and lower negative
  3. both positive
  4. upper negative and lower positive

A
upper negative and lower positive
B

C
Upper positive and lower negative
D
both positive
Solution
Verified by Toppr

The given figure shows the plot of lines of force due to two charges q1 and q2. Since for each charge, the lines of forces are directed radially inward i.e, towards the charge which implies that the charges are negative.
