Embibe Experts Solutions for Exercise 8: Assignment

In a region of space, both electric and magnetic field are present simultaneously in opposite directions. A positively charged particle is projected with certain speed an angle $\theta \left(<90°\right)$ with magnetic field. It will move in a

An electron is fired parallel to uniform electric and uniform magnetic field acting simultaneously and in the same direction. The electron

Due to the flow of current in a circular loop of radius $R$, the magnetic induction produced at the centre of the loop is $B$. The magnetic moment of the loop is $\left({\mu }_0=\right.$ permeability constant)

A length $I$ of a wire is bent to form a circular coil of some turns. A current $i$ is then established in the coil and it is placed in a uniform magnetic field $B$. The maximum torque that acts on the coil is

A ring carrying current $I$ lies in $x-z$ plane as shown. A short magnetic dipole with dipole moment directed along $x$-axis is fixed at origin. If the ring is free to move anywhere, then it will

Two galvanometers $A$ and $B$ require $3 \mathrm{mA}$ and $5 \mathrm{mA}$ respectively to produce the same deflection of $10$ division then

The restoring couple in the moving coil galvanometer is due to

In an attempt to increases the current sensitivity of a moving coil galvanometer, it is found that its resistance becomes double while the current sensitivity increases by $10\%$. The voltage sensitivity of the galvanometer changes by
