$A$ body of mass $5 \ kg$ is suspended by a spring balance on an inclined plane as shown in the figure. The spring balance measures (in $N$):

$A$ block of mass $M$ is at rest on a plane surface inclined at an angle $\theta$ to the horizontal. The magnitude of the force exerted by the plane on the block is

Why are mountain roads generally made winding upwards rather than going straight up?

If $M_1 = M_2$ and $\theta = 30^o$,then the acceleration is ........... $ms^{-2}$.

$A$ solid sphere,a hollow sphere,and a ring are released from the top of a frictionless inclined plane. They slide down the plane. Which object will have the maximum linear acceleration at the bottom of the plane? The objects do not roll on the plane.

The time taken by a block of wood (initially at rest) to slide down a smooth inclined plane $9.8 \ m$ long (angle of inclination is $30^o$) is ......... $sec$.
