21. Determine the radius of curvature of an electron in a magnetic field of 1 Wb/m2 when its speed is given by (a) B = 0.3; (b) B = 0.99; (c) B = 0.999. Take mc² = 0.5 MeV. (Ans. (a) 5.225 x 10 m; (b) 1.17 cm; (c) 3.723 cm) 22. What is the radius of curvature of a proton (moc² = 1000 MeV) of velocity 3 x 10' m/s in a magnetic (Ans. 0.335 m) 23. At what fraction of the speed of light does a particle travel if its kinetic energy is (a) equal to its rest (Ans. (a) 0.866; (b) 0.943) field of 1 T? mass energy (b) twice its rest mass energy? 21.
