Question

two blocks of iron of different masses are kept on a cemented floor as shown in figure which one of them would require a larger force to move it from the rest position​

Answer 1

$\huge\underline\mathfrak\red{Solution}$

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

Answer 2

Answer:

Block B with 2 units would require a larger force to move it from the rest position. This is because when an object is heavier then there is more interlocking of irregularities. So, the static friction increases.
