Two vectors ` vec A and vec B` are added. Prove that the magitude of the resultant v ector

When two vector vec a and vec b are added,the magnitude of the resultant vector is always

Two vectors vec(P) " and "vec(Q) are added, the magnitude of resultant is 15 units. If vec(Q) is reversed and added to vec(P) resultant has a magnitude sqrt(113) units. The resultant of vec(P) and a vector perpendicular vec(P) and equal in magnitude to vec(Q) has a magnitude

The resultant of two vectors vec A and vec B perpendicular to the vector vec A and its magnitude id equal to half of the magnitude of the vector vec B . Find out the angle between vec A and vec B .

The resultant of two velocity vectors vec(A) and vec(B) is perpendicular to vec(A) . Magnitude of Resultant vec(R ) is equal to half magnitude of vec(B) . If the angle between vec(A) and vec(B) is (30 theta)^(@) , then value of theta is ?

The resultant of two vectors vec(P) and vec(Q) is vec(R) . If vec(Q) is doubled then the new resultant vector is perpendicular to vec(P) . Then magnitude of vec(R) is :-

Two vectors vec(a) and vec(b) are at an angle of 60^(@) with each other . Their resultant makes an angle of 45^(@) with vec(a) If |vec(b)|=2 unit , then |vec(a)| is

Two vectors vec A and vec B are such that vec A + vec B = vec A- vec B , then

Two vectors vec(A) and vec(B) inclined at an angle theta have a resultant vec(R ) which makes an angle alpha with vec(A) . If the directions of vec(A) and vec(B) are interchanged, the resultant will have the same

Keeping one vector constant, if direction of other to be added in the first vector is changed continuously, tip of the resultant vector describes a circles, In the following figure vector vec(a) is kept constant. When vector vec(b) addede to vec(a) changes its direction, the tip of the resultant vector vec(r)=vec(a)+vec(b) describes circles of radius b with its centre at the tip of vector vec(a) . Maximum angle between vector vec(a) and the resultant vec(r)=vec(a)+vec(b) is

The resultant of two vectors vec A and vec B is perpendicular to the vector vec A and its magnitude is equal to half the magnitude of vector vec B . What is the angle between vec A and vec B ?
