If  and  are unit vectors along x, y and z axis respectively, then choose the wrong statement:

Two vectors  and  are given. Then which of the following options is/are correct?

If  is a unit vector and projection of  along  is 2 units and , then  is given by

Let  ,  and  be three given vectors. If  is a vector such that  and  then  is equal to

Let  and  be two vectors.

In 1D kinematics, the value of y and z components are just 1.Group of answer choicesTrueFalse
