Let 'O' be the origin and A, B be two points. bar(p), bar(q) are vectors represented by bar(OA), bar(OB) and their magnitudes are p, q respectively. Unit vector bisecting angleAOB is

Answer»

<P>`(BAR(p)/p+bar(Q)/q)/ABS(bar(p)/p+bar(q)/q)`
`(bar(p)/p-bar(q)/q)/abs(bar(p)/p-bar(q)/q)`
`bar(p)/p+bar(q)/q`
`bar(p)/p-bar(q)/q`
