Rotational Dynamics
A slob is subjected to two force $$\overset{\rightarrow}{F_1}$$ and $$\overset{\rightarrow}{F_2}$$ of same magnitude $$F$$ as shown in the figure .Force $$\overset{\rightarrow}{F_2}$$ is in $$XY-$$ plane while force $$\overset{\rightarrow}{F_1}$$ acts along $$z-$$axis at the point $$(2\overset{\rightarrow}{i}+3\overset{\rightarrow}{j})$$. The moment of these forces about point O will be :

A uniform disc is acted by two equal forces of magnitude F. One of them, acts tangentially to the disc, while other one is acting at the central point of the disc. The friction between disc surface and ground surface is nF. If r be the radius of the disc, then the value of n would be? (in N)
