An object is placed in a uniform electric field. If the charge of the object is positive, which direction will it move? A. Against the direction of the electric field B. In a direction perpendicular to the electric field C. In the same direction as the electric field D. It will not ...
The force exerted by an electric charge at the origin on a charged particle at a point (x,y,z) with position vector = x,y,z is ()=(K)(||^3) where K is a constant. Find the work done as the particle moves along a straight line from (2,0,0) to (2,1,5). 相关知识点:...
electric charge- the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; "the battery needed a fresh charge" charge electrostatic charge- the electric charge at rest on the surface of an insulated body (which establishe...
