A proton travels few distance in an electric field, then it enters a crossed magnetic field of 1 T1 \mathrm{~T} and radius 0.2 m0.2 \mathrm{~m}, find the velocity of proton.

Options

  1. A0.2×108 m s−10.2 \times 10^8 \mathrm{~m} \mathrm{~s}^{-1}
  2. B0.2×107 m s−10.2 \times 10^7 \mathrm{~m} \mathrm{~s}^{-1}
  3. C0.2×106 m s−10.2 \times 10^6 \mathrm{~m} \mathrm{~s}^{-1}
  4. D2×107 m s−12 \times 10^7 \mathrm{~m} \mathrm{~s}^{-1}

Correct answer

A. 0.2×108 m s−10.2 \times 10^8 \mathrm{~m} \mathrm{~s}^{-1}

Step-by-step solution

Given, B=1 T,r=0.2 mB=1 \mathrm{~T}, r=0.2 \mathrm{~m} r=mvqB\frac{m v}{q B}i.e, v=0.2×1.6×10−19×11.6×10−27=0.2×108 m s−1\quad v=\frac{0.2 \times 1.6 \times 10^{-19} \times 1}{1.6 \times 10^{-27}}=0.2 \times 10^8 \mathrm{~m} \mathrm{~s}^{-1}
