Vectors
If ABCD is parallelogram with AC and BD as diagonals, then (vector AC - vector BD) = ?

a) 4(vector AB)
b) Vector AB
c) 2(vector AB)
d) 3(vector AB)



Answer
Correct Answer Is : 2(vector AB)
Solution Is :
If vector c = 2(vector a) - 3(vector b) and 2(vector c) = 3(vector a) + 4(vector b), then vector c and vector a are?

a) At right angles
b) Like parallel vectors
c) Unlike parallel vectors
d) None of these



Answer
Correct Answer Is : Like parallel vectors
Solution Is :
Vectors (p, q) and (5, 1) are parallel, if

a) Pq = 5
b) Q = 5 p
c) P + q = 5
d) P = 5 q



Answer
Correct Answer Is : P = 5 q
Solution Is :
In a triangle ABC, if 2(vector AC) = 3(vector CB), then 2(vector OA) + 3(vector OB) equals?

a) 5(vector OC)
b) Vector OC
c) [-(vector OC)]
d) None of these



Answer
Correct Answer Is : 5(vector OC)
Solution Is :
ABCDEF is a regular hexagon and vector AB = vector a, vector BC = vector b and vector CD = vector c, then vector AE is?

a) Vector c + vector a
b) Vector a + vector b + vector c
c) Vector b + vector c
d) Vector a + vector b



Answer
Correct Answer Is : Vector b + vector c
Solution Is :
If three points A, B and C have position vectors (1, x, 3), (3, 4, 7) and (y, -2, -5) respectively and if they are collinear, then (x, y) = ?

a) (-2, 3)
b) (2, -3)
c) (2, 3)
d) (-2, -3)



Answer
Correct Answer Is : (2, -3)
Solution Is :
In a triangle ABC, vector AB = vector a, vector AC = vector c, vector BC = vector b, then ?

a) Vector a + vector b + vector c = 0
b) Vector a + vector b - vector c = 0
c) Vector a - vector b + vector c = 0
d) (-vector a + vector b + vector c) = 0



Answer
Correct Answer Is : Vector a + vector b - vector c = 0
Solution Is :
If vector a and vector b are two non-zero and non-collinear vectors, then vector a + vector b and vector a - vector b are?

a) Linearly dependent vectors
b) Linearly dependent and independent vectors
c) Linearly independent vectors
d) None of these



Answer
Correct Answer Is : Linearly independent vectors
Solution Is :
If a = (1, -1) and b = (-2, m) are two collinear vectors, then m =?

a) 3
b) 4
c) 0
d) 2



Answer
Correct Answer Is : 2
Solution Is :
If C is the midpoint of AB and P is any point outside AB, then ?
