    A particle is simultaneously acted by two forces equal to 4 N and 3 N. The net force on the particle is       [CPMT 1979]

    A)                 7 N        

    B)                 5 N

    C)                 1 N        

    D)                 Between 1 N and 7 N

    Correct Answer: D

    Solution :

                        If two vectors \[\vec{A}\]and \[\vec{B}\] are given then the resultant \[{{R}_{\text{max}}}\] = \[A+B=7N\]and \[{{R}_{\min }}=4-3=1N\] i.e. net force on the particle is between 1 N and 7 N.
