Three forces of magnitude $6 \mathrm{N}, 6 \mathrm{N}$ and $\sqrt{72} \mathrm{N}$ act at a cormer of a cube along three edges of a cube, as shown in the figure. The resultant of the three forces is

Two equal forces are acting at a point, making an angle of $60°$ with each other. If their resultant force is equal to $40\sqrt{3} \mathrm{N},$ the magnitude of each force is $\underline{ }$

Force of friction and tension in a string are ___________ in origin

A body of mass $2 \mathrm{kg}$ moves with an acceleration $3{ \mathrm{m} \mathrm{s}}^{-2}$. The change in momentum in one second is:

A force acts on a body of mass $50 \mathrm{kg},$ for $10$ seconds. When the force stops acting on the body, the body covers $80 \mathrm{m}$ in the next $10$ seconds. What is the magnitude of the force?

A body is at rest on the surface of the earth which of the following statements is correct?

When a lift of mass $800 \mathrm{kg}$ is ascending with an acceleration of $5 \mathrm{m} {\mathrm{s}}^{-2}$, the tension in its cable will be $\_\_\_\_\_\_$ take $(\left.\mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$

The coefficient of friction $\text{'}\mu \text{'}$ and the angle of friction $\text{'}\lambda \text{'}$ are related by _______
