Question

Resultant of scalar product and vector product of two given vectors is zero .if one vector is i^. What is the other vector

Answer 1

assume the other vector is a vector.

(i)a vector . î = 0 (let) so it means the angle btwn them is 90degree

(ii)a vector *î=0(to get the resultant as 0)

it means that the angle btwn the vectors is 0 degree.

But this case is impossible as 2 vectors can never b perpendicular and parallel at the same time. So the other vector has to be a null vector i.e. 0 to fulfill the condition the question is demanding

Answer 2

Answer:

Ans Is null vector.

Explanation:

As two lines can't be parallel and perpendicular at same time
