Which of the following is self adjusting in nature?
Rolling frictional force
Static frictional force
Kinetic frictional force
All of these
A heavy body of mass $25\, kg$ is to be dragged along a horizontal plane $\left( {\mu = \frac{1}{{\sqrt 3 }}} \right).$ The least force required is ........ $kgf$
The limiting friction between two bodies in contact is independent of
In the figure shown, a block of weight $10 \,N$ resting on a horizontal surface. The coefficient of static friction between the block and the surface ${\mu _s} = 0.4$. A force of $3.5\, N$ will keep the block in uniform motion, once it has been set in motion. A horizontal force of $3 \,N$ is applied to the block, then the block will
What is the maximum value of the force $F$ such that the block shown in the arrangement does not move ....... $N$
The tension $T$ in the string shown in figure is
