Question

If a= i + 6j + k and b= i + 15j + k , find the unit vector with positive first coordinate that is orthogonal to both a and b.

Answer 1

let c be the vector orthogonal to bothe . for obtaining c just find out the cross product of given vectors . then divide c with mod(C) to get unit vector . you vcan always multiply with + or -1 throughout to get positive term on x

Answer 2
