The angle between the two vectors vecA and vecB shown in the figure is theta. The magnitude of their resultant vector...

The angle between vector (vecA) and (vecA-vecB) is :

If the angle between two vectors vecA and vecB " is " 90^(@) then

The angle between vectors (vecA xx vecB) and (vecB xx vecA) is :

If the angle between the vectors vecA and vecB is theta, the value of the product (vecB xx vecA) * vecA is equal to

Magnitude of the cross product of the two vectors (vecA and vecB) is equal to the dot product of the two . Magnitude of their resultant can be written as

The value of the sum of two vectors vecA and vecB with theta as the angle between them is

The resultant of two vectors vecA and vecB" is "vecC . If the megnitude of vecB is doubled, the new resultant vector becomes perpendicular to vecA , then the magnitude of vecC is

If two vectors vecA and vecB are at an angle theta ne 0^(@) , then

Let the angle between two nonzero vector vecA and vecB is 120^@ and its resultant be vecC .
