Solution

The correct option is B $0.02$
frictional force= $μ m g$
$200 = μ 1000 \times 10$
$μ = 0.02$

A block of mass 5 kg is lying on a rough horizontal surface. The coefficients of static and kinetic friction between the block and the surface respectively are 0.7 and 0.5. A horizontal force just sufficient to move the block is applied to it. If the force continues to act even after the block has started moving, what will be the acceleration of the block? Take $g = 10 m s^{- 2}$ .
