A) \[210\,kg\]
B) \[190\,kg\]
C) \[185\,kg\]
D) \[162\,kg\]
Correct Answer: D
Solution :
[d] Maximum friction that can be obtained between A and B is \[{{f}_{1}}=\mu {{m}_{A}}g=(0.3)(100)(10)=300N\] and maximum friction between B and ground is \[{{f}_{2}}=\mu ({{m}_{A}}+{{m}_{B}})g=(0.3)(100+140)(10)=720N\]Drawing free body diagrams of A, B and C in limiting case, we getYou need to login to perform this action.
