Question

what is surface charge density and specific gravity?​

Answer 1

Answer:

Surface Charge Density:-

The surface charge density on a solid is defined as the total amount of charge q per unit area A.

Specific Gravity:-

(i)The specific gravity of an object is the ratio between the density of an object to a reference liquid.

(ii)The specific gravity has no units. If the specific gravity has a value of greater than one, then the object sinks in water and if it is less than one, then the object floats in water.
