A body of mass $5\,kg$ is suspended by a spring balance on an inclined plane as shown in figure. The spring balance measure ............ $N$

A

$50 $

B

$25$

C

$500$

D

$10 $

Solution

(b) Since downward force along the inclined plane

=$mg\sin \theta $$ = 5 \times 10 \times \sin 30^\circ $= $25\,N$

Two blocks $1$ and $2$ of equal mass $m$ are connected by an ideal string (see figure below) over a frictionless pulley. The blocks are attached to the ground by springs having spring constants $k_1$ and $k_2$ such that $k_1 > k_2$. Initially, both springs are unstretched. Block $1$ is slowly pulled down a distance $x$ and released. Just after the release the possible values of the magnitudes of the accelerations of the blocks $a_1$ and $a_2$ can be

One end of a massless spring of spring constant $k$ and natural length $l_{0}$ is fixed while the other end is connected to a small object of mass $m$ lying on a frictionless table. The spring remains horizontal on the table. If the object is made to rotate at an angular velocity $\omega$ about an axis passing through fixed end, then the elongation of the spring will be
