(a, d)
From the diagram, it can be observed that Q 1 is positive and Q 2 is negative.
No. of lines on Q 1 is greater and number of lines is directly proportional to magnitude of charge.
So, |Q 1 | > |Q 2 |
Electric field will be zero to the right of Q 2 as it has small magnitude & opposite sign to that of Q 1
