What is the amount of work done in bringing a mass from the surface of Earth on one side to a point diametrically opposite on the other side?

Text Solution

Verified by Experts

The correct Answer is:
Isoelectric point: The `H^(+)` concentration at which the colloidal particles have no charge is known as the isoelectric point. At this point stability of colloidal particles becomes very less & do not move under influence of electric field.
