I am having some trouble with these question

3) An electron moves with a speed of 8.0 x 10 m/s along the +x-axis. It enters a region where there is a magnetic field of 2.5 T, directed at an angle of 60" to the +x-axis and lying in the xy-plane. (1 eV = 1.60 x 10-19 C, me] =9.11 x 10-31 kg) Calculate the magnitude of (a) the magnetic force on the electron. (b) the acceleration of the electron.The long straight wire in the figure carries a current / that is decreasing with time at a constant rate. The circular loops A, B, and C all lie in a plane containing the wire. The induced emf in each of the loops A, B, and C is such that A B C A) no emf is induced in any of the loops. B) loop A has a clockwise emf, loop B has no induced emf, and loop C has a counterclockwise emf. C) loop A has a counter-clockwise emf, loop B has no induced emf, and loop C has a clockwise emf. D) a counterclockwise emf is induced in all the loops. E) loop A has a counter-clockwise emf, loops B and C have clockwise emfs
