Resultant of two vectors `vec(3p) and vec(2p)` is R. If first vector is doubled then the resultant is also doubled. Calculate the angle between the two vectors.

Resultant of vectors 3P and 2P is vector R. When the first vector is doubled, R also doubles. Find the angle between the two vectors.

2P and P are two vectors inclined to each other at such an angle that if the 1 st vector is doubled , the value of the resultant becomes three times. What is the angle between the two vectors ?

Magnitude of each of two vectors is P. Magnitude of the resultant of the two is also P. angle between the vectors is

The maximum magnitude of the resultant of two vectors, vec(P) and vec(Q) ("where" Pgt Q) is x times the minimum magnitude ot the resultant. When the angle between vec(P) and vec(Q)" ""is" " "theta , the magnitude of the resultant is equal to half the sum of the magnitudes of the two vectors. Prove that, cos theta =(x^2+2)/(2(1-x^2))*

For any two vectors vec(a) " and " vec(b) which of the following is true?

If the resultant of two equal vectors P is P then find out the angle between them.

The magnitude of each of the two vectors are P the magnitude of resultant vector of them is also P. The angle between two vectors are:

The resultant of two vectors of magnitude 3 unit and 4 unit is 5 unit. The angle between these two vectors will be---

vecR is the resultant of two vectors vecP and vecQ . When vecQ is reversed , the resultant is vecS . Prove that R^2+S^2=2(P^2+Q^2) .
