CBSE Class 11-science - Introduction to Vectors Videos
Motion in a Plane
This video explains scalars, vectors, position and displacement vectors and the addition of vectors by the triangle method.
-
A×B where A= 2i-3j-k and B =i+4j-2k
- 1.State paralogram law of vector addition and derive magnitude and the direction of a resultant vector
- What do your understatnd by (1)position vector and (ii) displancment vector. Distinguish them with illustration.
- what is dot product
- a boat's speed in still water is 20km/h .if the boat is to travel directly across a river whose current has a speed of 12km/h ,at what upstream angle must the boat head?
- A particle is located at 5i^ +6j^ + 7k^ at t=0.. After 5 seconds, it is located at 2i^+5j^ +5k^. The magnitude of displacement of the particle in XY plane is: ???
- if |A|=|B|=|A-B|, then find the angle b/w the two vectors
- how to find component of vector ?
-
