Is it possible to add 2 vectors of unequal magnitudes and to get zero ?

no i dont think it is possible......bcos if u want 0 the corresponding i,j,k should sum up to 0 and since there are only 2 vectors one coefficient has to be the -ve of the other so while taking mag it comes out to be the same

it is not possible to get summation of two vectors of diff magnitude as zero ...
because for two verctors if they r in opp direction then they can be algebraically subtracted but if their magnitudes are diff then their subtraction is not equal to 0
if A=B and they r in opp direction then their resultant is 0 but if their mag is diff then their resultant cant be 0
acc to me this should b the ans
correct me if i m wrong

ya possible if vectors form closed loop...

no nt psbl.2 frm a closed loop u need atleast 3 vectors
|
there are two rules to succeed
1.never tell everything you know.
2.never tell you know everything.

There must be at least 3 vectors for this to happen. Its not possible in case of 2 vectors.

yes to have magnitude as zero there must be minimum of 3 vectors in a plane bt in a space there must b minimum of 4 vectors to get mag as zero...
rate me if my ans is useful.......
