TRUE OR FALSE.

Electric field is essential in studying the concept of electro-cardio vascular diseases.

Source Charge

This is also known as the point charge; the charge which produce electric field and It is a large charge through which electric fields flow.

Test Charge

A vanishingly small positive charge that is used to detect the presence of an electric field.

Contact Force

In Mechanical Physics, these are forces that require physical contact between two objects

Field Force

Also known as non-contact force; This is a vector field corresponding with a non-contact force acting on a particle at various positions in space.

Field

This is a function that is used to specify the spatial distribution of a physical quantity.

Electric Field

This is a type of field force that is affected by charges.

Magnetic Field

This is a type of field force affected by magnetic property.

Gravitational Field

This is a type of field force affected by mass.

Michael Faraday

He is an English scientist probably best known for his discovery of electromagnetic induction, his contributions to electrical engineering and electrochemistry or due to the fact that he was responsible for introducing the concept of field in physics to describe electromagnetic interaction.

Electric Field

This is the invisible force area around a charge object.

Electric Field Lines

These are imaginary lines used to represent the direction and magnitude of an electric field.
