1. Electric Charges and Fields
easy
Why does matter obtain electric charge ?
Option A
Option B
Option C
Option D
Solution
All matter is made up of atoms and/or molecules.
Although normally the materials are electrically neutral, they do contain charges; but their charges are exactly balanced.
Forces that hold the molecules together, forces that hold atoms together in a solid, the adhesive force of glue, forces associated with surface tension, all are basically electrical in nature, arising from the forces between charged particles.
Thus, the electric force is all pervasive.
