Answer: An equipotential surface must be perpendicular to the electric field at every point. The correct option is B.
Explanation: Equipotential surface is any surface over which the potential difference is constant. Examples include:
-The surface of a conductor in electrostatic field.
- surface of a liquid in equilibrium.
Equipotential surface are perpendicular to the electric field at every point because components of electric field intensity along the surface is zero ( this is because no work is done while moving a charge from one point to another on an equipotential surface).
Weathering, erosion, impact, pressure
That’s actually correct!! Good luck with the test
There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
