Find a unit vector perpendicular to both the vectors ( ) ( ) 2iˆ + 3 ˆj + kˆ and iˆ − ˆj + 2kˆ. is  (1) (1) (7iˆ + 3 ˆj − 5kˆ) / 83 2  (2) (7iˆ − 3 ˆj − 5kˆ) / 83 (2) 3 (3) (7iˆ + 3 ˆj + 5kˆ) / 83 (3)  (4) (−7iˆ + 3 ˆj − 5kˆ) / 83  (4) 4 3. If two vectors 2iˆ + 3 ˆj − kˆ and −4iˆ − 6 ˆj −kˆ are 7. If iˆ, ˆj and kˆ are unit vectors along X, Y and Z axis antiparallel to each other, then value of  will be respectively, then tick the wrong statement: (1) 0 (2) –2 (3) 3 (4) 4 (1) iˆ  iˆ = 1 (2) iˆ  ˆj = kˆ (3) iˆ  ˆj = 0 (4) iˆ  kˆ = −iˆ 4. If A = 3iˆ + ˆj + 2kˆ and B = 2iˆ − 2 ˆj + 4kˆ , then value of A  B will be 8. If for two vectors A and B, A B = 0 , the vectors (1) 8 2 (2) 8 3 (1) Are perpendicular to each other (3) 8 5 (4) 5 8 (2) Are parallel to each other (3) Act at an angle of 60° (4) Act at an angle of 30°  2 Note: Kindly find the Video Solution of DPPs Questions in the DPPs Section.
