Questions  

The x-component of the resultant of several vectors
a) is equal to the sum of the x-components of the vectors
b) may be smaller than the sum of the magnitudes of the vectors
c) may be greater than the sum of the magnitudes of the vectors
d) may be equal to the sum of the magitudes of the vectors

a
only a
b
a, b & d
c
a, b, & c
d
b & d

detailed solution

Correct option is B

Sum of vectors a⇀,b⇀and c⇀is R⇀as shown in the figure.Magnitude of x-component of R =OMMagnitudfe of x-Component of  a⇀= OKMagnitude of x-Component of b⇀=  KLMagnitude of x-Component of C⇀= LMNow OM = OK + KL+LMAlso , OK < OA , KL < AB and BC > LMSo option - (2 ) is right
