Question

Find the resultant of two vectors A→ and B→ acting perpendicularity at a point.​

Answer 1

Answer:

When two vectors a and b are added , the magnitude of the resultant vector is always. Two vectors of equal magnitude are added to give resultant which is same magnitude as the two vecto... Two vectors each of magnitude A have a resultant of same magnitude A.

Answer 2

Answer:

PLS MARK ME AS BRAINALIST PLS

I ALSO MARK U AS A BRAINALIST PLS MARK ME AS BRAINALIST PLS SIR OR MADAM

Explanation:

2B=A2+B2+2ABcosθ ....(i)

∴tan90o=A+BcosθBsinθ⇒A+Bcosθ=0

∴cosθ=−BA

Hence, from (i) 4B2=A2+B2−2A2⇒A=32B

⇒cosθ=−BA=−23∴θ=150o
