Two masses $m$ and $M$ are attached to the strings as shown in the figure. If the system is in equilibrium, then
Define impulse of force. Time derivative of momentum gives which physical quantity ?
Three forces starts 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
In the figure, the tension in the horizontal cord is $30\,N$. Find the weight of the body $B.$ ............ $N$
A jet of liquid of cross-sectional area $'a'$ strikes a wall making angle $\theta $ with wall. The water strikes with the wall with velocity $v$ and rebounds elastically. If density of liquid be $\rho $, the normal force on the wall is
