An iron rod of volume ${10^{ - 4}}\,{m^3}$ and relative permeability $ 1000$ is placed inside a long solenoid wound with $5 $ $turns/cm$. If a current of $0.5 \,A $ is passed through the solenoid, then the magnetic moment of the rod is....$A{m^2}$

In an ink-jet printer, an ink droplet of mass $m$ is given a negative charge $q$ by a computer-controlled charging unit, and then enters at speed $v$ in the region between two deflecting parallel plates of length $L$ separated by distance $d$ (see figure below). All over this region exists a downward electric field which you can assume to be uniform. Neglecting the gravitational force on the droplet, the maximum charge that can be given so that it will not hit a plate is close to :

Two vibrating tuning forks produce progressive waves given by ${Y_1} = 4\sin 500\pi t$ and ${Y_2} = 2\sin 506\pi t.$ Number of beats produced per minute is

A frictionless pulley is attached to one arm of a balance and a string passed around it carries two masses $m_1$ and $m_2$. The pulley is provided with $a$ clamp due to which $m_1$ and $m_2$ do not move $w.r.t.$ each other. On removing the clamp, if the counter mass restores balance, then acceleration of centre of mass of the masses $m_1$ and $m_2$ will have acceleration of magnitude ?

The gravitational potential at a point above the surface of earth is $-5.12 \times 10^7 \mathrm{~J} / \mathrm{kg}$ and the acceleration due to gravity at that point is $6.4 \mathrm{~m} / \mathrm{s}^2$. Assume that the mean radius of earth to be $6400 \mathrm{~km}$. The height of this point above the earth's surface is :

A particle is placed at the origin and a force $F = kx$is acting on it (where $k$ is positive constant). If $U(0) = 0$, the graph of $U(x)$ versus x will be (where $U$ is the potential energy function)

An electron collides with a free molecule initially in its ground state. The collision leaves the molecule in an excited state that is metastable and does not decay to the ground state by radiation. Let $K$ be the sum of the initial kinetic energies of the electron and the molecule and $p$ be the sum of their initial momenta. Let $K^{\prime}$ and $p ^{\prime}$ represent the same physical quantities after the collision. Then,

$Assertion$ : There are very small sporadic changes in the speed of rotation of the earth
$Reason$ : Shifting of large air masses in the earth's atmosphere produce a change in the moment of inertia of the earth causing its speed of rotation to change.
