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.

![eduncle-logo-app]()
option c is correct...
![eduncle-logo-app]()
for any doubt u can ask..

mam kindly tell me how we came to know that A & D are wrong just by viewing them as in hint please let me know !???
![eduncle-logo-app]()
dear, A, D is clearly wrong because the charges are not equal so the e.f at the point p( at z-aixs) is not along z-axis, also not along x-axis.. simply draw lines of e.f at point p by both charges.. note when charges are equal then at point p, e.f is along z- axis because the negative x and positive x components will cancel and only z component will remain same. therefore in this case the x components will not cancel and u will have x component also along with z component.. hope u will get me..
