  4. A rectangular wooden block 5 cm × 10 cm × 10 cm in size is kept on a horizontal surface with its face of largest area on the surface. A minimum force of 1.5 N applied parallel to the surface sets the block in sliding motion along the surface. If the block is now kept with its face of smaller area in contact with the surface, the minimum force applied parallel to the surface, to set the block in motion, is

Q. A rectangular wooden block in size is kept on a horizontal surface with its face of largest area on the surface. A minimum force of applied parallel to the surface sets the block in sliding motion along the surface. If the block is now kept with its face of smaller area in contact with the surface, the minimum force applied parallel to the surface, to set the block in motion, is

Solution:

force of friction is independent of the area of contact
