Coefficient of Friction Between Body and Edge
Category : JEE Main & Advanced
Coefficient of Friction Between Body and Edge A body slides on a smooth wedge of angle \[\theta \] and its time of descent is t. If the same wedge made rough then time taken by it to come down becomes n times more (i.e. nt) The length of path in both the cases are same.
For smooth wedge \[S=u\,t+\frac{1}{2}a{{t}^{2}}\] \[S=\frac{1}{2}(g\,\sin \theta )\,{{t}^{2}}\] .....(i) \[[\text{As}\,u=0\,\text{and }\]\[a=g\sin \theta ]\] | For rough wedge \[S=u\,t+\frac{1}{2}a{{t}^{2}}\] \[S=\frac{1}{2}g\,(\sin \theta -\mu \cos \theta )\,{{(nt)}^{2}}\] .....(ii) \[[\text{As}\,u=0\,\text{and}\,a=g\,(\sin \theta -\mu \,\cos \theta )]\] |
