MCQ
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$1\, N$
- ✓Between $1\, N$ and $7 \,N$
${R_{{\rm{max}}}}$ = $A + B = 7N$ and ${R_{\min }} = 4 - 3 = 1N$
i.e. net force on the particle is between $1\, N$ and $7 \,N.$
