heya friend,
its quite easy question
see the steps:
A=3i+4j and B =i-j , in x-y plane.
Let their resultant be
R , Thus R = 3i+4j + i - j => 4i -3j
We know resultant to two vectors is given by
R = √A²+B²+2ABcos∅
Here ∅ = 90° since the vectors are perpendicular to each other
thus R = √4²+(-3)²+0 => 5
Answer is 5
Hope this helps!!!!!!!!
