NEET Physics Moving Charges and Magnetism Questions Solved


A proton of mass 1.67×10-27kg and charge 1.6×10-19C is projected with a speed of 2×106m/s at an angle of 60° to the X- axis. If a uniform magnetic field of 0.104 Tesla is applied along Y- axis, the path of proton is 

(a) A circle of radius = 0.2 m and time period π×10-7s

(b) A circle of radius = 0.1 m and time period 2π×10-7s 

(c) A helix of radius = 0.1 m and time period 2π×10-7s

(d) A helix of radius = 0.2 m and time period 4π×10-7s
