Two blocks of iron of different masses are kept on a cemented floor as shown in Fig.12.2. Which one of them would require a larger force to move it from the rest position?

Question

Philoid · Accepted Answer

The second block having mass 2 units would require a larger force to move it from the rest position because:

⇒ As the mass of the object increases, the force of friction increases.

⇒ Hence, second block (mass 2units) will be having more force of friction.

⇒ Thus, it need larger force to move the heavier block from the rest position.
