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
Direction of zero vector
does not exist
is towards origin
is indeterminate
None of these
The component of a vector is
always less than its magnitude
always greater than its magnitude
always equal to its magnitude
A vector whose magnitude is of unit length is called
zero vector
unit vector
position vector
collinear vector
If the position vectors of A and B are
If and are the position vectors of A and B, then position vector of a point C on AB produced such that AC = 3AB is
If , then the value of is
The non-zero vectors , and are related by = 8 and = -7. Then, the angle between and is
π
0
π/4
π/2
If , then the magnitude of ( + ) is
13
-13
3
4
If is a vector of magnitude 21 and has direction ratios 2,-3,6, then value of is
