Two vectors and are equal if
their magnitudes are equal
they originate from the same point
their direction is same
their magnitude as well as direction is same
If , then the unit vector in the direction of is
If and are the position vectors of A and B, then position vector of a point C on AB produced such that AC = 3 AB is
If the position vectors of A and B are
A vector whose magnitude is of unit length is called
zero vector
unit vector
position vector
collinear vector
Let be three non-zero vectors such that no two of these are collinear. If the vector + 2 is collinear with , then + 2 + 6 equals
λ (λ ≠ 0, a scalar)
0
Direction of zero vector
does not exist
is towards origin
is indeterminate
None of these
ABCDEF is a regular hexagon with center at the origin such that . Then λ is equal to
2
4
6
8
The component of a vector is
always less than its magnitude
always greater than its magnitude
always equal to its magnitude
If = (2,1,-1), = (1,-1,0), =(5,-1,1) then unit vector parallel to but in opposite direction is
