A wedge as shown in figure has a rough curved surface of coefficient of kinetic friction `(1)/sqrt(3)` whose shape can be given by equation `y=x^(2)`, where the horizontal direction is x-axis, vertical direction as y axis and the end of surface O as origin and x `&` y are measured in meter. A small block is released, from a certain point on the surface. The maximum height of the point from where block should be released so that it does not slip. A. `(1)/(4)m`B. `(1)/(6)m`C. `(1)/(12)m`D. `(1)/(16)m` |

Answer» Correct Answer - C For no slipping `tantheta=mu=(dy)/(dx)=2x=(1)/sqrt(3)` `rArrx=(1)/(2sqrt(3))rArry=x^(2)=(1)/(12)m` |
