A light spring balance hangs from the hook of the other light spring balance and a block of mass M Kg hangs from the former one. Then the true statement about the scale reading is :
Three forces start acting simultaneously on a particle moving with velocity $\vec{v}$. These forces are represented in magnitude and direction by the three sides of a triangle ABC (as shown ). The particle will now move with velocity 
A car is moving on a plane inclined at $30^a$ to the horizontal with an acceleration of $10 \mathrm{~ms}^{-2}$ parallel to the plane upward. A bob is suspended by a string from the roof of the car. The angle in degrees which the string makes with the vertical is: (Take $\mathrm{g}=10 \mathrm{~ms}^{-2}$ )

When a body is in equilibrium
Concepts Covered - 1
Equilibrium of concurrent forces
-
Concurrent Forces-If all the forces working on a body are acting on the same point then they are said to be concurrent.
-
Three forces will be in equilibrium if they are represented by three sides of a triangle taken in order.
-
For equilibrium,
$\begin{aligned} & \sum \overrightarrow{F_{n e t}}=0 \\ & \text { or } \sum \vec{F}_x=0, \sum \vec{F}_y=0, \sum \vec{F}_z=0\end{aligned}$
- Lami’s theorem: It states that for three concurrent forces in equilibrium,
$\frac{F_1}{\sin \alpha}=\frac{F_2}{\sin \beta}=\frac{F_3}{\sin \gamma}$
