![]() The strength (magnitude) of the electric field is indicated by.(Actually, the direction of the electric force is tangent to the The electric force on a small positive test charge at that point. (b) The direction of an electric field line is in the direction of (a) Electric field lines are a pictorial description of theĮlectric field, developed by the great 19th century physicist.Space is the direction of the electric force on a small positive Its magnitudeĪt any point equals the magnitude of the electric force that aĬharged object would feel at that point divided by the magnitude Magnitude and a direction at every point in space. An electric field is a vector quantity because it has both a.(c) they both decrease in magnitude inversely as the square of the (b) they both transmit forces between objects, (a) are vector fields - that is, they both involve both magnitude The gravitational and electric fields are both similar in that.In the case of the electric force, a charged object creates anĮlectric field in the surrounding space, and other charged objects Instance) feel the effect of the gravitational field. In the space around it, and other objects with mass (like you, for With mass (the Earth, for instance) creates a gravitational field In the case of the gravitational force, an object Problem" by having the field act as the intermediary between the The concept of a field gets around the "action at a distance.The gravitational force and the electric force are both "action at "Action at a distance" refers to the notion of an objectĮxerting a force on a second object without touching it.Physics Assignment Answers - Chapter 33 Answers for
