A uniform rope of length l lies on a table. If the coefficient of friction is $\mu $, then the maximum length ${l_1}$ of the part of this rope which can overhang from the edge of the table without sliding down is
$\frac{l}{\mu }$
$\frac{l}{{\mu + l}}$
$\frac{{\mu l}}{{1 + \mu }}$
$\frac{{\mu l}}{{\mu - 1}}$
A man balances himself in a horizontal position by pushing his hands and feet against two parallel walls. His centre of mass lies midway between the walls. The coefficients of friction at the walls are equal. Which of the following is not correct?
Two blocks $A$ and $B$ are released from the top of a rough inclined plane so that $A$ slides along the plane and $B$ falls down freely. Which will have higher velocity on reaching the ground ?
For the given figure, if block remains in equilibrium position then find frictional force between block and wall ........ $N$
What is the maximum value of the force $F$ such that the block shown in the arrangement does not move ....... $N$
A force of $19.6\, N$ when applied parallel to the surface just moves a body of mass $10 \,kg$ kept on a horizontal surface. If a $5\, kg$ mass is kept on the first mass, the force applied parallel to the surface to just move the combined body is........ $N.$
