Find the direction of the resultant of two vectors A and B in terms of their magnitudes and angle θ between them.

Options

  1. Atanα = AsinθA+Bcosθtan\alpha ~=~\frac{Asin\theta }{A+Bcos\theta }
  2. Btanα = BsinθA+Bcosθtan\alpha ~=~\frac{Bsin\theta }{A+Bcos\theta }
  3. Ctanα = BsinθB+Acosθtan\alpha ~=~\frac{Bsin\theta }{B+Acos\theta }
  4. Dtanα = AsinθB+Acosθtan\alpha ~=~\frac{Asin\theta }{B+Acos\theta }

Correct answer

B. tanα = BsinθA+Bcosθtan\alpha ~=~\frac{Bsin\theta }{A+Bcos\theta }

Step-by-step solution

Correct Option is : (B)
tanα = BsinθA+Bcosθtan\alpha ~=~\frac{Bsin\theta }{A+Bcos\theta }
