By adding three unit vectors is it possible to get a unit vector ?

Text Solution

Verified by Experts

If any two unit vectors out the three are equal in magnitude but opposite in direction , then adding all the three vectors we obtain a resultant equal to the third unit vector. For instance , on adding `veca,-veca and vecb`, we get, `veca+(-veca)+vecb=vecb`.
