Question

answer this 28 question of physics

Answer 1

let normal reaction between two block is N1 ,and the normal reaction between biggger block and ground in N2

for smaller block

so mg - T -μ1N1 =m2a.....1

 N1=ma .............2

 for bigger block

N2 =Mg +μ1N1 +T

   or  N2=Mg + mg-2ma (from equation 1).......3

and  T +T -N1 -μ2N2=Ma

       2T -ma -μ2(Mg +mg-2ma) =Ma ........4

put value of T from equation 1

2(mg -μ1ma-2ma) -ma -μ2(Mg +mg-2ma) =Ma

solve for a
Hope so it will help u☺☺☺☺
