If A B =(2 i +3 j - k ) and A(1,2,-1) is the given point, then the coordinates of B are

Options

  1. A(2,4,1)
  2. B(3,5,2)
  3. C(3,5,-2)
  4. D(2,4,-1)

Correct answer

C. (3,5,-2)

Step-by-step solution

Let B(x, y, z) then A B =(x-1) i +(y-2) j +(z+1) k aligned & x-1=2, y-2=3 and z+1=-1 & x=3, y=5 and z=-2 & B (3,5,-2) aligned
