Unformatted text preview: Physics 21 Fall, 2009 Solution to HW-10 27-1 A particle with a charge of q = 1 . 10 10 8 C is moving with instantaneous velocity v = (5 . 00 i 3 . 70 j ) m/s. (a,b,c) Find the x , y , and z components of the force exerted on this particle by a magnetic field B = 1 . 50 i T. (d,e,f) Find the x , y , and z components of the force exerted on this particle by a magnetic field B = 1 . 50 k T. (a,b,c) F = q v B = q ( v x i + v y j ) B i Using i i = 0 and j i = k leads to F = qv y B k = 6 . 11 10 8 N k (d,e,f) F = q v B = q ( v x i + v y j ) B k Using i k = j and j k = i leads to F = qB ( v y i v x j ) = (6 . 11 10 8 i + 8 . 25 10 8 j ) N 27.6 An electron moves at v = 2 . 20 10 6 m/s through a region in which there is a magnetic field of unspecified direction and magnitude B = 8 . 00 10 2 T. (a) What is the largest possible magnitude of the acceleration a of the electron due to the magnetic field? (b) What is the smallestelectron due to the magnetic field?...
