Q. A body of mass $2$ $kg$ is placed on a horizontal surface having coefficient of kinetic friction $0.4$ and coefficient of static friction $0.5$. If a horizontal force of $2.5$ $N$ is applied on the body, the minimum force required to slide the body is( take $g=10m/s^2$) :

Q. A body of mass 2 kg is placed on a horizontal surface having kinetic friction 0.4 and static friction 0.5 If force applied on body is 20 Newton find acceleration of body

Q. A body of mass $5kg$ is placed on a rough horizontal surface. If coefficients of static and kinetic friction are $0.5$ and $0.4$ respectively, then find the value of force of friction when external applied horizontal external force is (i) $15N$ (ii) $25N$ and (iii) $35N$

Q. A body of mass $2kg$ is placed on a horizontal surface having kinetic friction $0\cdot 4$ and satic friction $0\cdot 5$. If the force applied on the body is $2\cdot 5N$, then the frictional force acting on the body will be
