Question

Two particles are located at equal distance from origin. The position vectors of those are represented by A=2i+3nj+2k and B=2i-2j+4pk, respectively. If both the vectors are at right angle to each other, the value of n^-1 is ________.

Accepted Answer

Correct answer: 3. (3) A B=0 4-6n+8p=0 | A |= |B | 4+9n^2+4=4+4+16p^2 9n^2=16p^2 P=+ 34n 4-6n 6n=0 12n=4 n= 13

$Two particles are located at equal distance from origin. The position vectors of those are represented by A = 2 i + 3 nj + 2 k and B = 2 i - 2 j + 4 p k, respectively. If both the vectors are at right angle to each other, the value of n^{- 1} is ________.$
