Given that ab˙=0and a×b=0. What can you conclude about the vectors aand b.
If D,EandF are three points on the sides BC,CAandAB, respectively, of a triangle ABC such that the CDBD,AECE,BFAF=−1
If the resultant of two forces is equal in magnitude to one of the components and perpendicular to it direction, find the other components using the vector method.
Let ABC be triangle, the position vecrtors of whose vertices are respectively i^+2j^+4k^ , -2i^+2j^+k^and2i^+4j^−3k^ . Then DeltaABC is a. isosceles b. equilateral c. right angled d. none of these
What is the unit vector parallel to a=3i^+4j^−2k^ ? What vector should be added to a so that the resultant is the unit vector i^?
