List one gives certain physical quantity and List - II gives there magnitude.
List - IList - II(I) Acceleration of 2 kg(P) 0(II) Acceleration of 4 kg(Q) 3(III) Acceleration of 6 kg(R) 6(IV) Friction between 2 kg & 4 kg(S)83(T)163(U)185
If external force of 40 N is applied horizontly on 4 kg block, Correct match for acceleration and friction is
