A $1 \mathrm{~kg}$ mass is suspended from the ceiling by a rope of length $4 \mathrm{~m}$. A horizontal force ' $F$ ' is applied at the mid point of the rope so that the rope makes an angle of $45^{\circ}$ with respect to the vertical axis as shown in figure. The magnitude of $F$ is:
$\frac{10}{\sqrt{2}} \mathrm{~N}$
$1 \mathrm{~N}$
$\frac{1}{10 \times \sqrt{2}} \mathrm{~N}$
$10 \mathrm{~N}$
In the given arrangement, the normal force applied by block on the ground is
For a free body diagram shown in the figure, the four forces are applied in the ' $x$ ' and ' $y$ ' directions. What additional force must be applied and at what angle with positive $x$-axis so that the net acceleration of body is zero?
What is dynamics ?
A body of mass $5\,kg$ is suspended by a spring balance on an inclined plane as shown in figure. (in $N$)
If net force on a system is zero then
