Let a,b and c be three unit vectors such that `3a+4b+5c=0`. Then which of the following statements is true?

A

a is parallel to b

B

a is perpendicular to b

C

a is neither parallel nor perpendicular to b

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
`3a+4b+5c=0`
Hence, a,b and c are coplanar.
No other conclusion can be derived from it.
