2. (a) Find the angle between the two vectors A= 2î + 4j – 4k andB= –2î + 2j – k.
(b) Find C= AX B (Remember that this is vector product.)
Vectors A and B have scalar product -7.00, and their vector product has magnitude +9.00. What is the angle
between these two vectors?
.
Use the definition of scalar product, a
two vectors given by a = 5.0 + 5.0
b = ab cos 0, and the fact that a b = axbx + aby + a2b₂ to calculate the angle between the
+ 5.0k and b = 7.01 +3.0 + 3.0k.

(b) AB is smaller than AB. (c) AB could be larger or smaller than AB, depending on the angle between the vectors. (d) AB could be equal to AB.arrow_forwardIf the cross product of two vectors vanishes, what can you say about their directions?arrow_forwardA mysterious force acts on all particles along a particular line and always points towards a particular point P on the line. The magnitude of the force on a particle increases as the cube of the distance from that point; that is Fr3 , if the distance from P to the position of the particle is r. Let b be the proportionality constant, and write the magnitude of the force as F=br3.
