Subjective Put a uniform meter scale horizontally on your extended index fingers with the left one at 0 00 cm and the right one at 90 00 cm When you attempt to move both the fingers slowly towards the center initially only the left finger slips with respect to the scale and the right finger does not After some distance the left finger stops and the right one starts slipping Then the right finger stops at a distance XR from the center 50 00 cm of the scale and the left one starts slipping again This happens because of the difference in the frictional forces on the two fingers If the coefficients of static and dynamic friction between the fingers and the scale are 0 40 and 0 32 respectively the value of XR in cm is 2020
