Moment of a force of magnitude 10 N acting along positive $y$-direction at point $(2 \mathrm{~m}, 0,0)$ about the point $(0,1 \mathrm{~m}, 0)$ in $\mathrm{N}-\mathrm{m}$ is
The ratio of the acceleration for a solid sphere (mass $$m$$ and radius $$R$$) rolling down an incline of angle '$$\theta$$' without slipping down the incline without rolling is.
A particle of mass $m$ is projected with a velocity $$v$$ making an angle of $$45^{\circ}$$ with the horizontal. The magnitude of angular momentum of the projectile about the point of projection when the particle is at its maximum height $$h$$ is.
A uniform cube of side $a$ and mass $m$ rests on a rough horizontal table. A horizontal force $F$ is applied normal to one of the faces at a point that is directly above the centre of the faces at a point that is directly above the centre of the face at a height 3a/4 above the base. The minimum value of F for which the cube begins to topple an edge is (assume that cube does not slide)
