If the vector -bar(i)+bar(j)-bar(k) bisects the angles between the vector bar(c) and the vector 3bar(i)+4bar(j), then the unit vector in the direction of bar(c) is

Answer»

`11bar(i)+10bar(J)+2BAR(K)`
`-(11bar(i)+10bar(j)+2bar(k))`
`-1/15(11bar(i)+10bar(j)+2bar(k))`
`1/15(11bar(i)+10bar(j)+2bar(k))`
