11) An electron at point A of mass m = 9.11 -10 * kg and a charge q = -1.6*10*** Centers a uniform magnetic B with a velocity v = 1.41X10° 3 m/s and is bent in a semicircle of diameter 10 cm, as shown in the figure. Find a) the magnitude and the direction of the magnetic field B (+k is out of the page) b) the time it takes the electron to cover the semi-circular path. 10.0 cm
12) A charged particle of charge q = + 3.20 x 10-C and of mass m=6.7x10 kg moves with a velocity v = (2km/s through a region where both a uniform electric field E = (-i +2]wim and a uniform magnetic field B. What would the magnetic field B =(Bi+B IT if the charged particle passes through the fields un deflected?
