Calculate $T_1$ and $T_2$
$\frac{{\sqrt 3 }}{2}mg,\frac{{mg}}{2}$
$mg,\frac{{\sqrt 3 }}{2}mg$
$\frac{{\sqrt 3 }}{2}mg,\frac{{\sqrt 3 }}{2}mg$
$\frac{{mg}}{2},\frac{{mg}}{2}$
Write different type of common forces.
A mass of $2\, kg$ suspended with thread $AB$ (figure). Thread $CD$ of the same type is attached to the other end of $2\, kg$ mass. if the lower thread is pulled with a jerk, what happens ?
A block of $\sqrt{3}\,kg$ is attached to a string whose other end is attached to the wall. An unknown force $F$ is applied so that the string makes an angle of $30^{\circ}$ with the wall. The tension $T$ is $...........\,N$ :(Given $g =10\,ms ^{-2}$ )
A false balance has equal arms. An object weigh $X$ when placed in one pan and $Y$ when placed in other pan, then the weight $W$ of the object is equal to
Figure shows $(x,\, t)$, $(y,\, t)$ diagram of a particle moving in $2-$ dimensions.
If the particle has a mass of $500\,g$, find the force (direction and magnitude) acting on the particle.
