A marble block of mass $2\, kg$ lying on ice when given a velocity of $6\, m/s$ is stopped by friction in $10s$. Then the coefficient of friction is-
$0.02$
$0.03$
$0.06$
$0.01$
Why coefficient friction is considered as static friction ?
The limiting friction between two bodies in contact is independent of
Static friction between two surfaces
A uniform chain of $6\, m$ length is placed on a table such that a part of its length is hanging over the edge of the table. The system is at rest. The co-efficient of static friction between the chain and the surface of the table is $0.5$, the maximum length of the chain hanging from the table is.......$m.$
A block is stationary on a rough inclined plane. How many forces are acting on the block?
