Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

it's like conceptual question. As charge kept between both of these positive charges is independent of sign as it will be kept at the equilibrium position so options A and B are only remaining to answer from these if the charge is kept near to +4Q then it will attract the new charge more strongly so if it is kept near the charge +Q then it will also attract but athe same time another charge +4Q also attracts it so it will be in equilibrium when it is kept near to +Q. Hence the b option is correct
you may also solve it but takes time
