Electric Charge and its basic Properties

In general, metallic ropes are suspended on the carriers which take inflammable material. The reason is

A body is having $-2\mathrm{C}$charge. If ${10}^6$ electrons move out of the body every second, then time after which the body becomes neutral will be approximately

A conductor is containing a charge of$-5 \mathrm{\mu C}.$ The numbers of electrons contained by the conductor are

 A body is having $-2 \mathrm{C}$ charge. If ${10}^6$ electrons move out of the body every second, then time after which the body becomes neutral will be approximately
 

What are electrons?

Spheres A and B having equal masses are given charges$+ q$  and $- q$ respectively. If after charging their respective masses are respectively 
$m_A$ and $m_{\mathit{B}}$, then relation of $m_A$ and $m_B$ will be _____.

Find the charge on an iron particle of mass $2.24 \mathrm{mg}$ if $0.02 \%$ of electrons are removed from it.

The charge present in a doubly ionized helium atom is

A charge $\frac{2Q}{3}$ is to be divided on two objects. The value of charge on each object, such that force between the object can be maximum, would be

How many electrons must be removed from a body so that it may have the charge of

i. $1 \mathrm{million} \mathrm{coulombs}$

ii. $1 \mathrm{micro} \mathrm{coulomb}$

High concentration of positive charges implies$:$

How many electrons may be removed from a body so that it may have a charge (a) $+1 \mathrm{milli} \mathrm{coulomb}$, (b) $+1 \mathrm{micro} \mathrm{coulomb}$.

Four identical metallic sphere $A,B,C,D$. Sphere $A$ carries charge $q$, sphere $B$ carries $q$, sphere $C$ and $D$ are uncharged. Sphere $C$ touches $A$ and sphere $D$ touches $B$. Calculate the force between two spheres $A$ and $B$ if distance between them is halved.

What is static electricity?
