two blocks of masses ma=2kg and mb=4kg are kept on an inclined plane of inclination  = 37degree as shown.The coefficient of friction bw A and B is  1 and bw B and surface is 2. accelerations of blocks A and B are a1 and a2. then match the following. column I column II 1.a1=a2 A. 1= 0.3 and 2 = 02.a1  a2 B 1= 0.8 and 2 = 0.83.if work done by friction on block B is zero,then C. 1= 0 and 2 = 0.24.if net contact force on block A is normal force,then D.
1= 0.4 and 2 = 0.8 |
