WB JEE 2021 Physics - Laws of Motion Question 12 English

Three blocks are pushed with a force F across a frictionless table as shown in figure above. Let N₁ be the contact force between the left two blocks and N₂ be the contact force between the right two blocks. Then,

F > N₁ > N₂

F > N₂ > N₁

F > N₁ = N₂

F = N₁ = N₂

A block of mass m rests on a horizontal table with a coefficient of static friction $$\mu $$. What minimum force must be applied on the block to drag it on the table?

$${\mu \over {\sqrt {1 + {\mu ^2}} }}$$ mg

$${{\mu - 1} \over {\mu + 1}}$$ mg

$${\mu \over {\sqrt {1 - {\mu ^2}} }}$$ mg

$$\mu $$ mg

Two weights of the mass m₁ and m₂ (> m₁) are joined by an inextensible string of negligible mass passing over a fixed frictionless pulley. The magnitude of the acceleration of the loads is

$${{{m_2} - {m_1}} \over {{m_2}}}$$

$${{{m_1}} \over {{m_2} + {m_1}}}g$$

$${{{m_2} - {m_1}} \over {{m_2} + {m_1}}}g$$
