An ideal spring is compressed and placed...


An ideal spring is compressed and placed horizontally between a vertical fixed wall and a block free to slide over a smooth horizontal table to as shown in the figure. The system is released from rest. The graph which represents the relation between the magnitude of acceleration `a` of the block and the distance `x` travelled by it (as long as the spring is compressed) is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C

Let the initial compression of spring be l. Then the acceleration after the block travels a distance x is
`a=(k)/(m)(l-x)`
The graph of a vs. x is

Two blocks are connected by a long inextensible string passing over an ideal pulley as shown in the figure. If the system is released from rest then the common speed of blocks when block m_2 moves a distance I will be

An ideal spring is permanently connected between two blocks of masses M and m . The blocks-spring system can move over a smooth horizontal table along a straight line along the length of the spring as shown in Fig.The blocks are brought nearer to compress the spring and then released.
