Question

agram below each unit on the horizontal axis is 5.00 cm and each unit on the vertical axis is 5.00 cm. The equipotential lines in a region of uniform electric field are indicated by the blue lines. (Note that the diagram is not drawn to se 6 V 12 V 24 V (a) what is the direction of the electric field? Determine the magnitude of the electric field in this region. the delirnition of electric field in terms of potential difference and distance? V/m the shortest distance for which the change in potential is 3 V

Explanation / Answer

E = dV/dr

dV = 6V

dr = 5cos45 .... because the units make an isoceles right angled triangle with same sides of length 5cm. Height of the triangle is the distance between equipotential lines

= 3.535 cm = 0.03535 m

E = 6/0.03535 = 169.73 V/m

b)

similarly

E = dV/dr

169.73 = 3/dr

dr = 0.01768 m
