Explain. port Vector 3 How would you define the zero vector 0? DEL

Explanation / Answer

vactor1 : components of zero vector will also be zero.

x = y = z = 0

hence magnitude = sqrt(x^2 + y^2 + z^2) = 0

so zero vector can not have non-zero magnitude.

vector 2: if magnitude is zero.

x^2 + y^2 + z^2 = 0

so x^2 , y^2 and z^2 all are +ve quantity.

so x = y = z = 0

zero magnitude can not have non-zero components

Vector 3: zero vector is vector with all its component zero.

(its a point in space with zero magnitude and no direction)
