012 points I Previous Answers My Notes I SerPSE9 29. P.0222 Assume the region to the right of a certain plane contains a uniform magnetic field of magnitude b T and the field is zero in 1.80 the region to the left of the plane as shown in the figure below. An electron originally traveling perpendicular to the boundary plane, passes into the region of the field x x x x x x X X X X X (a) Determine the time interval required for the electron to leave the "field-filled" region, noting that the electron's path is a semicircle 1.99E-8 Your response differs from the correct answer by more than 100% s (b) Assuming the ma mum depth of penetration into the field is cm, find the kinetic energy of the electron 2.57 3.01E-19 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. eVExplanation / Answer
kin energy E=0.5m*v^2 = 0.5*m*(qBr/m)^2 =
= 0.5m*q*(?q*B*r/m)^2 =
= q*0.5* 9.1091e-31*(?1.602e-19 *1.8e-3*2.57e-2 /9.1091e-31)^2=
= q*188.17= 188.17 eV
