Which of the following properties is $NOT$ satisfied by a static electric charge?

An insulating solid metal sphere is charged with a charge $+Q$. The distribution of $+Q$ charge on the surface will be .......

We have three identical metallic spheres $A, B$ and $C$. $A$ is given a charge $Q$,and $B$ and $C$ are uncharged. The following processes of touching of two spheres are carried out in succession. Each process is carried out with sufficient time.
$(i)$ $A$ and $B$
$(ii)$ $B$ and $C$
$(iii)$ $C$ and $A$
$(iv)$ $A$ and $B$
$(v)$ $B$ and $C$
The final charges on the spheres are

Write the unit and value of the fundamental electric charge.

When a body is connected to the earth,electrons from the earth flow into the body. This means the body is initially:

The vehicles carrying inflammable fluids usually have metallic chains touching the ground:
