assertion reason
- Vector A = 2i + 3j + k (where i, j, and k are unit vectors along the x, y, and z axes respectively) Vector B = 1i + 2j - 2k Find the magnitude (length) of the vector resulting from the cross product of A and B (A x B).

two forces whose magnitude are in the 3:5 give a resultant f Jatio 3:5 give 20 N. If fac 20. It fue angle of thread indination of each face find Magnitude

please provide complete solution
-
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.
