A metal block of mass 5kg lies on a rough horizontal platform. If a horizontal force of 8N applied to the block through its center of mass just slides the block on the platform, then the coefficient of limiting friction between the block and platform is

0.16

0.63

0.80

1.60

2.00

Answer Details

F = $μ$ R

= $μ$ mg

8 = $μ$ x 5 x 10

$μ$ = 0.16
