Question

Two bodies $A$ and $B$ of masses $10 \,kg$ and $15\, kg$ respectively kept on a smooth, horizontal surface are tied to the ends of a light string. If T represents the tension in the string when a horizontal force $F=500 \,N$ is applied to $A$ (as shown in figure $1$) and $T$ be the tension when it is applied to $B$ (figure $2$), then which of the following is true?

• A. $T=T=500\,N$
• B. $T=T=250\,N$
• C. $T=200\,N,T=300\,N$
• D. $T=300\,N,T=200\,N$

Answer 1

Answer: (D)

$T=300\,N,T=200\,N$

Answer 2

For the first case acceleration $a=\frac{F}{m_{1}+m_{2}}$
