    Solution Verified by Toppr

    Correct option is B)

    Maximum magnitude of static friction force=0.4×5×10m/s

    2 =20N

    Now the force applied on the block is 25N, while the static frictional force is 20N, this implies that both the slab & box will move at different acceleration rates.

    From Newton's second law,

    N sb ​ =m block ​ ×g F−f k ​ =m block ​ ×g Also, f k ​ =m slab ​ ×a slab ​ and f k ​ =μ k ​ ×N sb ​ ⇒m slab ​ ×a slab ​ =μ k ​ ×N sb ​ ⇒m slab ​ ×a slab ​ =μ k ​ ×m block ​ ×g ⇒a slab ​ = m slab ​ μ k ​ ×m block ​ ×g ​ = 20 0.2×5×10 ​ =0.5m/s 2

    Two block problem Question

    A block B of mass 5kg is placed on a slab A of mass 20kg which lies on a frictionless surface as shown in the figure. The coefficient of static friction between the block and the slab is 0.4 and that of kinetic friction is 0.2. If a force F = 25N acts on B, the acceleration of the slab will be

    Easy Solution

    Maximum force up to which A and B will move together is given by μ

    μ Fmax=μsmg(1+m/M)

    where m = mass of B and M = mass of A.

    ∴Fmax=0.4×5×10(1+5/20)N⇒25N

    A and B will move together and their acceleration is
