Two masses $m$ and $M$ are attached to the strings as shown in the figure. If the system is in equilibrium, then
$tan\theta = 1 +\frac{{2M}}{m}$
$cot\theta = 1 + \frac{{2M}}{m}$
$tan\theta = 1 + \frac{{2M}}{m}$
$cot\theta = 1 + \frac{{2M}}{m}$
A body of mass $5\,kg$ is suspended by a spring balance on an inclined plane as shown in figure. (in $N$)
A piece of wire is bent in the shape of a parabola $y=k x^2$ ( $y$-axis vertical) with a bead of mass $m$ on it. The bead can slide on the wire without friction. It stays at the lowest point of the parabola when the wire is at rest. The wire is now accelerated parallel to the $x$-axis with a constant acceleration $\alpha$. The distance of the new equilibrium position of the bead, where the bead can stay at rest with respect to the wire, from the $y$-axis is
A rope of length $5\,m$ is kept on frictionless surface and a force of $5\,N$ is applied to one of its end. Find tension in the rope at $1\,m $ from this end ......... $N$
When milk is churned, cream gets separated due to
An iron sphere weighing $10\, N$ rests in a $V$ shaped smooth trough whose sides form an angle of $60^o$ as shown in the figure. Then the reaction forces are
