Electric Charge and Its Properties

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

What is electrostatics?

 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 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 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.

A particle of mass $m$ has charge $q_0$ when it is at rest. When the particle moves with speed $v$, charge on the particle will becomes ($c$ is velocity of light in vacuum)

Two metallic spheres $A$ and $B$ of equal size each having charge $+12 \mathrm{\mu C}$ and a third sphere $C$ of different size carries charge of $-11 \mathrm{\mu C}$. What will be the charge of sphere $C$, if each of sphere $A$ and $B$ carries charge of $+3 \mathrm{\mu C}$ after making contact between three spheres?

An electron at rest has a charge of $1.6\times {10}^{-19} \mathrm{C}$. It starts moving with a velocity $v=\frac{c}{2}$, where $c$ is the speed of light, then the new charge on it is-

What is the difference between electric charge and mass.

If five charges are as follows $+q, +3q, -2q, -6q, +8q$, then what is total charge value?

For the addition of the charge, which one of the given things should be taken care of?

For the invariance of the charge, which of the given can be varied?

An insulated metallic sphere $\left(x\right)$ is charged and is covered by another insulated hollow metallic sphere $\left(y\right)$. If a connection is made between the two,

When ${10}^{19}$ electrons are removed from a neutral metal plate, the electric charge on it (in coulomb) is 

A positively charged glass rod is brought close to a metallic rod isolated from ground. The charge on the side of the metallic rod away from the glass rod will be

When a positively charged body is brought near the metal disc of a neutral electroscope, its leaves -

If an object has a net charge of $-1 \mathrm{C}$, the number of excess electrons possessed by it is?

To give a charge of $4.8\times {10}^{-19} \mathrm{C}$ to some object, how many electrons are to be removed from it? ($e=1.6\times {10}^{-19} \mathrm{C}$)
