A mass of $100\,kg$ is moved with uniform velocity under the influence of force $F$, then the force acting on the beam due to string connected to the ceiling ............ $N$

A$1470$

B$1760$

C$960$

D$490$

Solution

$2 \mathrm{T}=100 \mathrm{g}$
$\Rightarrow \mathrm{T}=50 \mathrm{g}$
$ \text { Force on the beam is } 3 \mathrm{T}=3 \times 50 \times 9.8$
$=1470 \mathrm{N}$

A block of mass $2 M$ is attached to a massless spring with spring-constant $k$. This block is connected to two other blocks of masses $M$ and $2 M$ using two massless pulleys and strings. The accelerations of the blocks are $a_1, a_2$ and $a_3$ as shown in figure. The system is released from rest with the spring in its unstretched state. The maximum extension of the spring is $x _0$. Which of the following option($s$) is/are correct? [g is the acceleration due to gravity. Neglect friction]
