A) \[{{a}_{1}}>{{a}_{2}}\]
B) \[{{a}_{1}}<{{a}_{2}}\]
C) \[{{a}_{1}}={{a}_{2}}\]
D) None of these
Correct Answer: A
Solution :
Just before slipping occurs force acting on B is, \[{{\mu }_{s}}mg\], where m is the mass of block A. After the slipping the force on block B is \[{{\mu }_{K}}mg\]. Force before slipping is more, so acceleration before slipping should be more. |
