Question

A long block A of mass \(M\) is at rest on a smooth horizontal surface. A small block B of mass \(\frac M2\) is placed on A at one end and projected along A with some velocity \(v\). The coefficient of friction between the block is \(μ\). Then, the accelerations of blocks A and B before reaching a common velocity will be respectively.

• A. \(\frac {μ_g}{2}\) (towards right), \(\frac {μ_g}{2}\) (towards left)
• B. \(μ_g\) (towards right), \(μ_g\) (towards left)
• C. \(\frac {μ_g}{2}\) (towards right), \(μ_g\) (towards left)
• D. \(μ_g\) (towards right), \(\frac {μ_g}{2}\) (towards left)

Answer 1

The Correct Option is C

The correct option is (C): \(\frac {μ_g}{2}\) (towards right), \(μ_g\) (towards left).
