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 uniform rope of mass $M$ and length $L$ is fixed at its upper end vertically from a rigid support. Then the tension in the rope at the distance $l$ from the rigid support is $x$
For given systen ${\theta _2}$ ....... $^o$
What is dynamics ?
Which of the following is the correct order of forces
In a hydrogen atom, the distance between the electron and proton is $2.5 \times {10^{ - 11}}\,m$. The electrical force of attraction between them will be
