3-1.Vectors
easy
A particle is simultaneously acted by two forces equal to $4\, N$ and $3 \,N$. The net force on the particle is
A
$7\, N$
B
$5\, N$
C
$1\, N$
D
Between $1\, N$ and $7 \,N$
Solution
(d) If two vectors $\vec A$and $\vec B$ are given then the resultant
${R_{{\rm{max}}}}$ = $A + B = 7N$ and ${R_{\min }} = 4 – 3 = 1N$
i.e. net force on the particle is between $1\, N$ and $7 \,N.$
