shows a circular region of radius R = 3.50 cm in which an electric flux is directed out of the plane of the page. The flux encircled by a concentric circle of radius r is given by ΦE, enc = (0.819 V·m/s)(r/R)t, where r ≤ R and t is in seconds. What is the magnitude of the magnetic field that is induced at radial distances (a)2.50 cm and (b)7.00 cm

a. B = T

b. B = T

Explanation:

Given that:

the flux  ΦE,enc =

radius R = 3.50 cm = 0.0350 m

when r = 2.50 cm = 0.0250 m

Let B be the strength of the magnetic field inside then:

the magnitude of the magnetic field  that is induced at radial distance of 2.50 cm is:

B = T

Let B be the strength of the magnetic field outside then:

the magnitude of the magnetic field  that is induced at radial distance of 7.00 cm is:

B = T

none, its a machine

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
