two blocks of masses 5 kg and 10 kg, respectively, are placed on a table, as in the figure. the coefficients of friction between the blocks and the table are not the same. their respective values are indicated in the figure below each block. the blocks are connected by a string of negligible mass that can only withstand tension upto 100 n. a horizontal force is applied to the 10-kg block. what is the maximum value of the magnitude of that doesn't cause the string between blocks to break?
