One end of a spring is kept fixed while the other end is stretched by a force as shown in the diagram.

Copy the diagram and mark on it the direction of the restoring force.

One end of a spring is kept fixed while the other end is stretched by a force as shown in the diagram. Name one instrument which works on the above principle.

A book is kept on the table as shown in the diagram. Copy the diagram and mark the action reaction forces with their directions.

The diagram alongside shows a pulley arrangement : Copy the diagram and mark the direction of tension on each strand of the string.

A bead of mass m can slide without friction on a fixed circular horizontal ring of radius 3R having a centre at the point C. The bead is attached to one of the ends of spring of spring constant k. Natural length of spring is R and the other end of the spring is R and the other end of the spring is fixed at point O as shown in the figure. If the bead is released from position A, then the kinetic energy of the bead when it reaches point B is

An electric potential difference will be induced between the ends of the conductor shown in the diagram when it moves in the direction

Two light spring of force constants k_(1) and k_(2) and a block of mass m are in the line AB on a smooth horizontal table such that one end of each spring is fixed on right supports and the other end is free as shown in figure The distance CD between the free ends of the spring is 60 cm . If the block (k_(1) = 1.8 N//m, k_(2) = 3.2 N//m and m = 200g) . Is the motion simple harmonic?

Assertion: A spring has potential energy , both when it is compressed or stretched. Reason: In compressing or stretching, work is done on the spring against the restoring force.

A small block of mass m=1kg is attached with one end of the spring of force constant K=110Nm^-1 . Other end of the spring is fixed to a rough plane having coefficient of friction mu=0.2 . The spring is kept in its natural length by an inextensible thread ties between its ends as shown in figure. If the thread is burnt, calculate the elongation of the spring when the block attains static equilibrium position.

One end of a light spring of spring constant k is fixed to a wall and the other end is tied to a block placed on a smooth horizontal surface. In a displacment, the work done by the spring is +(1/2)kx^(2) . The possible cases are.

One end of a light spring of spring constant k is fixed to a wall and the other end is tied to a block placed on a smooth horizontal surface. In a displacement, the work done by the spring is +(1/2)kx^(2) . The possible cases are.
