The dot product of 2 vectors is 10 unit and the magnitude of their resultant is 6 units. If we rotate the vectors without changing the magnitude such that they are now perpendicular to each other, what is their new resultant.

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

A vector vecA is rotated through angle theta about its tail. Change of position vector of its tip of is:

A vector may change when we :

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.
