Embibe Experts Solutions for Exercise 2: Exercise 4.2

A $0.5 \mathrm{kg}(4.9 \mathrm{N})$ book rests on your desk. An additional force $F=1.1 \mathrm{N}$ is applied on this book in vertically downward direction. Normal reaction on this book will be?

A block of mass $2 \mathrm{kg}$ rest on the floor of an elevator. Which is moving down with an acceleration $\text{'}g\text{'}.$ Then the apparent weight of the block is (take, $g=10 \mathrm{m} {\mathrm{s}}^{-2}$ )

A block of mass $M$ is pulled along a smooth horizontal surface with a rope of mass $m$ by applying a force $F.$ The acceleration of the block will be

Calculate the tensions $T_1, T_2$ and $T_3$ in the three threads shown in the following figure. (All threads are massless) $\left(g=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$

A heavy block of mass $M$ hangs in equilibrium at the end of a rope of mass $m$ and length $l$ connected to a ceiling. Determine the tension in the rope at a distance $x$ from the ceiling.

A decoration, of mass $M,$ is suspended by a string from the ceiling inside an elevator. The elevator is traveling upward with a constant speed. The tension in the string is
