A uniform solid cylinder of mass M and radius R is placed on a rough horizontal board of same mass , which in turn is placed on a smooth surface . The coefficient of friction between the board and the cylinder is 𝜇=0.3 . If the board starts acceleration with constant acceleration a , as shown in the figure , then the maximum value of a , so that the cylinder performs pure rolling is ……………… m/𝑠^2 , g = 10 m/𝑠^2

1. using Kirchhoff law find the current in following branch answer     AB:(5/8) A, CA: (5/2) A, DEB: (15/8) A AD: (15/8) A, CD: 0 A, BC: (5/2) A 2.  using Kirchhoff law find the current in following branch   Answer  current in branch AB= (4/17) A In branch BC = (6/17) A In branch CD = (4/17) A In branch AD= (6/17) A In branch BD = (-2/17) A Total Current =(4/17) +(6/17)+(-4/17)+(6/17)+(-2/17)=(10/17) A 4. find R Equivalent
