Given in the figure are two blocks A and B of weight 20 N and 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 0.1 and between block B and the wall is 0.15, the frictional force applied by the wall on block B is
Text Solution
Verified by ExpertsThe correct answer is:
C
Assuming both the blocks are stationary
N = F
F 1 = 20N
f 2 = 100+20 = 120N
