Is it possible to add tow vectors of unequal magnitudes and get zero? Is it possible to add three vectors of e3qual magnitudes and get zero?

Assertion: The minimum number of vectors of unequal magnitude required to produce zero resultant is three. Reason: Three vectors of unequal magnitude which can be represented by the three sides of a triangle taken in order, produce zero resultant.

Minimum number of two coplanar vectors of equal magnitude whose vectors sum could be zero, is:

Given that vecA+vecB+vecC=0 , out of three vectors two are equal in magnitude and the magnitude of third vector is sqrt2 times that of either of two having equal magnitude. Then angle between vectors are given by

Find a vector of magnitude (5/2) units which is parallel to the vector 3hati+4hatj .

The minimum number of vectors of equal magnitude required to produce a zero resultant is :

Read each statement below carefully and state with reasons , if it is true of false : (a) The magnitude of a vector is always a scalar , (b) each component of a vector is always a scalar , (c ) the total path length is always equal to the magnitude of the displacement vector of a particle . (d) the average speed of a either greater or equal to the magnitude of average velocity of the particle over the same interval of time , (e ) Three vectors not lying in a plane can never add up to give a null vector .

The following sets of three vectors act on a body. Whose resultant cannot be zero ?

Show that a.(b × c) is equal in magnitude to the volume of the parallelepiped formed on the three vectors , a, b and c.
