Question

Which of the following is independent of choice of co-ordinate system @vectorP+vectorQ +vector R b. (vectorP+vectorQ +vector R)icap c.Pxi cap +Qy jcap+Rz kcap​

Answer 1

B,C

Because vector's length does not depend on coordinate system and also the vector direction will remain same.

But icap is just defined along x axis so if the coordinate system is changed, those will change

Answer 2

Answer:

The answer will be (A) that is P vector + Q vector + R vector.
