A force of 5 N acts on a particle along a direction making an angle of 60° with vertical. Its vertical component be

A)            10 N                                         

B)            3 N

C)            4 N

D)            2.5 N

Correct Answer: D

Solution :

             The component of force in vertical direction             =\[F\cos \theta =F\cos 60{}^\circ \]\[=5\times \frac{1}{2}\,\,=2.5\,N\]
