Does moving a charge along an equipotential surface do any work? The work done by the electric field on a particle when it is moved from one point on an equipotential surface to another point on the same equipotential surface is always zero. Why is there is no work done in moving a charge from […]

What does the strength of gravity between two objects depend on?
What does the strength of gravity between two objects depend on? The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects. Which of the following […]
Where is the net electric field zero?
Where is the net electric field zero? In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In Region III, the fields again point in opposite directions and there is a point where their magnitudes are the same. It is at this point where […]

What happens if one bulb goes out in a series circuit?
What will happen when oceanic crust converges with each other?
What will happen when oceanic crust converges with each other? If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the […]
