For L= 3 ax + 5 ay - 6 az, the amplitude for such a vector is approximately equal to ...

Two points L (3, 5, - 6) & Q (1, 3, 7), the vector LQ is equal to

• (-2, -2, 13)

• -2 ax - 2 ay + 13 az

• (2, 2, -13)

• 2 ax + 2 ay - 13 az

Two points L (3, 5, - 6) & Q (1, 3, 7), the vector QL is equal to

• (-2, -2, 13)

• -2 ax - 2 ay + 13 az

• (2, 2, -13)

• 2 ax + 2 ay - 13 az

Whether it is vector LQ or QL, the magnitude for both will be the same and equal to ...

L= 3 ax + 5 ay - 6 az & Q= ax + 3 ay + 7 az, then the scalar product between both vectors is equal to
