Block B of mass 2 kg is placed on block A of mass 4 kg which in turn is placed on smooth surface, coefficient of friction between blocks is 0.30. Horizontal force, F0 = 24 N is applied on block A. If acceleration of block A and B are aA and aB respectively, then [g = 10 m/s2]

2 kg द्रव्यमान के गुटके B को 4 kg द्रव्यमान के उस गुटके A पर रखा गया है जो चिकने पृष्ठ पर है, गुटकों के मध्य घर्षण गुणांक 0.30 है। गुटके A पर क्षैतिज बल F0 = 24 N आरोपित किया जाता है। यदि गुटके AB के त्वरण क्रमशः aAaB हैं, तब [g = 10 m/s2]
