For three vectors bar(p), bar(q) and bar(r)" if "bar(r)=3bar(p)+4bar(q) and 2bar(r)=bar(p)-3bar(q) then

Answer»

`ABS(BAR(r)) lt 2abs(bar(q)) and bar(r), bar(q)` have the same direction
`abs(bar(r)) GT 2abs(bar(q)) and bar(r), bar(q)` have the OPPOSITE direction
`abs(bar(r)) lt 2abs(bar(q)) and bar(r), bar(q)` have the opposite direction
`abs(bar(r)) gt 2abs(bar(q)) and bar(r), bar(q)` have the same direction
