A proton is moving with a uniform velocity of 10^6 ms^−1 along the Y−axis, under the joint action of a magnetic field along Z−axis and an electric field of magnitude 2×10^4 Vm^−1 along the negative X−axis. If the electric field is switched off, the proton starts moving in a circle. The radius of the circle is nearly (given : e/m ratio for proton ≈10^8Ckg^−1)
