Asserion: Magnitude of the resultant of two vectors may be less than the magnitude of either vector. Reason: The resultant of two vectors is obtained by means of law of parallelogram of Vectors.

Answer»


Solution :If `veca and vecb` are inclined at an ANGLE greater than `90^(@)`, their resultant has magnitude.
`R = SQRT(a^(2) + b^(2) + 2AB cos THETA)`
which is less than both a and b, when they are nearly EQUAL.
