153725 To a charged particle which is moving with a constant initial velocity $\overrightarrow{\mathbf{v}}$, uniform magnetic field is applied in the direction of the velocity

153726 An electron beam passes through a magnetic field of $2 \times 10^{-3} \mathrm{~Wb} / \mathrm{m}^{2}$ and an electric field of $1.0 \times 10^{4} \mathrm{~V} / \mathrm{m}$ both acting simultaneously. The path of electron remains undeviated.
The speed of electron if the electric field is removed and the radius of electron path will be respectively.

153728 When a proton is released from rest in a room, it starts with an initial acceleration $a_{0}$ towards West. When it is projected towards North with a speed $v_{0}$ it moves with an initial acceleration $3 \mathrm{a}_{0}$ towards West. The electric and magnetic fields in the room are

153730 If $E$ and $B$ are the magnitudes of electric and magnetic fields respectively in some region of space, then the possibilities for which a charged particle may move in that space with a uniform velocity of magnitude $v$ are
