Question

The position vector of the centre of the circle vertical line r with rightwards arrow on top vertical line equals 5 comma r with rightwards arrow on top times left parenthesis i with ˆ on top plus j with ˆ on top plus k with ˆ on top right parenthesis equals 3 square root of 3

  1. i with ˆ on top plus j with ˆ on top plus k with ˆ on top    
  2. 3 left parenthesis i with ˆ on top plus j with ˆ on top plus k with ˆ on top right parenthesis    
  3. left parenthesis square root of 3 plus i with ˆ on top plus k with ˆ on top right parenthesis    
  4. None of these    

The correct answer is: left parenthesis square root of 3 plus i with ˆ on top plus k with ˆ on top right parenthesis
