How many minimum number of non zero vectors in different planes can be adder to give zero resultant

In this item, we ask what is the minimum number of non-zero vectors that are directed towards the different direction that has to be summed up together to get a zero resultant vector. The answer to this item is three (3). Most often, these planes are known as the Planes X, Y, and Z. 

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
