Given in the figure are two blocks A and B of weight $\displaystyle 20$ N and $\displaystyle 100$ N, respectively. These are being pressed against a wall by a force F as shown. If the coefficient of friction between the blocks is $\displaystyle 0.1$ and between block B and the wall is $\displaystyle 0.15$, the frictional force applied by the wall on block B is :Official answer
