Question

Four identical blocks each of mass $m$ are kept on a horizontal frictionless plane in contact with adjacent blocks as shown in figure. A force $F$ is applied on the system.

• A. (A) acceleration of each block is $\frac{F}{4m}$
• B. (B) net force on the block $C$ is $\frac{F}{4}$
• C. (C) net force on the block $A$ is $\frac{3F}{4}$
• D. (D) force by the block $C$ on the $D$ is $\frac{F}{8}$

Answer 1

Answer: (A), (B)

The correct options are
A (A) acceleration of each block is $\frac{F}{4m}$
B (B) net force on the block $C$ is $\frac{F}{4}$
