For the resultant of two vectors A and B to maximum, the angle between them should be

Options

  1. A180^
  2. B0^
  3. C90^
  4. D60^

Correct answer

B. 0^

Step-by-step solution

We know that, the magnitude of resultant of two vectors A and B , R= A^2+B^2+2 A B Here, R R_ , when is maximum i.e. =1 =0^ Now, we get aligned R_ & = A^2+B^2+2 A B & =A+B aligned Hence, the resultant is maximum when angle between two vectors is 0^ .
