Answer:
sum of two perpendicular nonzero vectors can not be ZERO
Step-by-step explanation:
As we know by the sum or addition of two vectors is given by

here we know that
a and b are the magnitude of two vectors
= angle between two vectors
so as we know that here two vectors are perpendicular to each other
so we will have

now since the is sum of two positive non zero numbers so it can not be zero
so sum of two perpendicular nonzero vectors can not be ZERO
