Question

unit vector parallel to the resultant of vector 8i+8j will be

Answer 1

Answer:

Explanation:

A = 4i-3 j and B = 8 i +8 j

→→ Resultant of A and B, R = 121 + 51

Unit vector, R = R ↑R

↑R R=√12²+5² = 13

A 12 i + 5 j 13

Answer 2

Answer = (î + j)/√2

Note :- If we multiply any scalar by unit vector, it becomes vector quantity.
