The value of $\frac{T_3}{T_1}$ is .............

In which of the following cases is the contact force between $A$ and $B$ maximum $(m_A = m_B = 1 kg)$

$Assertion$ : A man and a block rest on smooth horizontal surface. The man holds a rope which is connected to block. The man cannot move on the horizontal surface

$Reason$ : A man standing at rest on smooth horizontal surface cannot start walking due to absence of friction (The man is only in contact with floor as shown).

A wedge of height $H$ (fixed) and inclination $\alpha $ (variable) is moving on a smooth horizontal surface with constant acceleration $g\ m/s^2$ . A small block is placed at bottom of incline as shown in figure, slips on the smooth surface of incline . Choose $CORRECT$ statement about time taken by block to reach the top of incline

Consider the following statements about the blocks shown in the diagram that are being pushed by a constant force on a frictionless table

$A.$All blocks move with the same acceleration

$B.$The net force on each block is the same

Which of these statements are/is correct

The tension in the string connected between blocks is ......... $N$
