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 boy is hanging from branch of a tree as shown. Angle between his arm, for tension to be maximum in arms must be ............ $^o$
$A$ flexible chain of weight $W$ hangs between two fixed points $A$ & $B$ which are at he same horizontal level. The inclination of the chain with the horizontal at both the points of support is $\theta$ . What is the tension of the chain at the mid point?
In the figure, blocks $A$ and $B$ of masses $2m$ and $m$ are connected with a string and system is hanged vertically with the help of a spring. Spring has negligible mass. Find out magnitude of acceleration of masses $2m$ and $m$ just after the instant when the string is cut
Which force act on body first action or reaction ?
Three blocks of masses ${m_1},\,{m_2}$ and ${m_3}$ are connected by massless strings as shown on a frictionless table. They are pulled with a force ${T_3} = 40\,N$. If ${m_1} = 10\,kg,\,{m_2} = 6\,kg$ and ${m_3} = 4\,kg$, the tension ${T_2}$ will be ........ $N$
