Answer 1

Answer:

the sum of two unit vectors is also a vector of

unit magnitude, the magnitude of the difference

of the two unit vectors is

1) 1 unit

2) 2 units

3) 13 units

4) Zero

ANS]

two unit vectors are A and B

↪There sum is =1,

|A + B|=1

A=|1-B|

↪Now difference ,

|A-B|=||1-B|+|B||

=1
