A)             2     

B)             3

C)                     4                                         

D)             5

Correct Answer: B

Solution :

                \[{{\vec{F}}_{3}}={{\vec{F}}_{1}}+{{\vec{F}}_{2}}\] There should be minimum three coplaner vectors having different magnitude which should be added to give zero resultant
