Q12 · Physics
The diagrams below show regions of equipotentials.
A positive charge is moved from A to B in each diagram.
The figure, described in words
Four equipotential diagrams (a)-(d): (a) straight lines 10 V, 20 V, 30 V, 40 V; (b) curved lines 10-40 V; (c) straight lines 10, 20, 30, 40 V widely spaced; (d) concentric arcs 10-40 V; in each A lies on 10 V/20 V side and B on 40 V side.
