Expert Answer:
Suppose a vector 
has components x, y and z along X, Y and Z axis respectively.
Magnitude of is given as 
For to be a zero vector, its magnitude must be zero.
In equation (1), R will be zero only if each of the components x, y and z are zero seperately.
i.e. R=0
=> x=y=z=0
has components x, y and z along X, Y and Z axis respectively. is given as to be a zero vector, its magnitude must be zero.Answered by | 10th Jul, 2011, 11:30: AM
