lets go by hit and trail method.If you take 1 vector, the resultant can never be zero.If you take 2 vectors, those should be in equal magnitude and opposite in direction for the resultant to be zero.If you take 3 vectors the resultant is zero. for example,let's take 3 vector's of unequal magnitude say 3 units, 2 units and -5 units, the resultant of these vectors is zero . we can take more than 2 vectors of unequal magnitude for the resultant to be zero.. so the minimum no.of vectors of unequal magnitude for the resultant to be zero and maximum is infinity.

but there is no option lake this
thnx
nice
can u solve one more
if cross product of vector P and Q is equal to zero vector and cross product of vector Q and R is equal to also zero vector then find the value of cross product of vector P and vector R
