Two blocks of iron of different masses are kept on a cemented floor as shown in the figure. Which one of them would require a larger force to move it from the rest position? "
The block having 2 unit mass will require a larger force to move as we know that friction increases as the mass increases. Therefore, a block having 2 unit mass will require a larger force to move from the rest rather than to move the block having 1 unit mass.
