# NEET Physics Moving Charges and Magnetism Questions Solved

A proton of mass $1.67×{10}^{-27}kg$ and charge $1.6×{10}^{-19}C$ is projected with a speed of $2×{10}^{6}m/s$ 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 $\mathrm{\pi }×{10}^{-7}\mathrm{s}$

(b) A circle of radius = 0.1 m and time period $2\mathrm{\pi }×{10}^{-7}\mathrm{s}$

(c) A helix of radius = 0.1 m and time period $2\mathrm{\pi }×{10}^{-7}\mathrm{s}$

(d) A helix of radius = 0.2 m and time period $4\mathrm{\pi }×{10}^{-7}\mathrm{s}$
