A unit vector has the magnitude of ___
a) 5
b) 1
c) 10
d) 0

The sum of two unit vectors is a unit vector then the magnitude of their difference is sqrt(3) . Prove this.

If the sum of two unit vectors is a unit vector, then magnitude of difference is-

Statement 1: Unit vector has a unit though its magnitude is one and Statement 2: Unit vector is obtained by dividing a vector by its own magnituded.

If magnitude of sum of two unit vectors is sqrt2 then find the magnitude of subtraction of these unit vectors.

Given a+b+c+d=0 , which of the following statements are correct (a) a,b,c and d must each be null vector , (b) The magnitude of (a+c) equals the magnitude of (b+d), (c ) The magnitude of a can never be greater than the sum of the magnitudes of b ,c and d, (d) b+c must lie in the plane of and d if a and d are not collinear , and in the line of a and d , if they are collimear ?

If the sum of two unit vectors is a unit vector,then find the magnitude of their differences.

If sum of two unit vectors is a unit vector; prove that the magnitude of their difference is sqrt3

Vector B has x,y and z components of 4.00,6.00 and 3.00 units, respectively. Calculate the magnitude of B and the angle that B makes with the coordinates axes.

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
