A proton travels few distance in an electric field, then it enters a crossed magnetic field of $1 T$ and radius $0.2 m$ , find the velocity of proton.

Options:

Answer:

Solution:

Given, $B = 1 T, r = 0.2 m$ $r = \frac{m v}{qB}$ i.e, $v = \frac{0.2 \times 1.6 \times 1 0 ^{- 19} \times 1}{1.6 \times 1 0 ^{- 27}} = 0.2 \times 1 0^{8} m s^{- 1}$
