The limiting friction is
A car accelerates on a horizontal road due to force exerted by
A body of mass $2$ kg is moving on the ground comes to rest after some time. The coefficient of kinetic friction between the body and the ground is $0.2$. The retardation in the body is ...... $m/s^2$
A marble block of mass $2\, kg$ lying on ice when given a velocity of $6 \,m/s$ is stopped by friction in $10\,s$. Then the coefficient of friction is
Given below are two statements:
$Statement$ $(I)$ : The limiting force of static friction depends on the area of contact and independent of materials.
$Statement$ $(II)$ : The limiting force of kinetic friction is independent of the area of contact and depends on materials.
In the light of the above statements, choose the most appropriate answer from the options given below:
