A beam of protons enters a uniform magnetic field of 0.3 tesla with a velocity of `4xx10^(5)` m/s at an angle of 60º to the field.  Then, (Mass of the proton `=1.7 xx10^(-27)` kg.)  (1) the radius of the helical path is `1.226 xx 10^(-2)` m   (2) the pitch of the helix is `4.45 xx 10^(-2)` m   (3) the radius of the helical path is `1.226 xx 10^(-3)` m  (4) the pitch of the helix is `4.45xx10^(-4)` m
