In a gravity free space a charged particle is projected. If the kinetic energy of the particle charges but it suffers no deviation, then in that region of space

• A

  E and B both must be zero

• B

  ‘E’ must be zero but ‘B’ may not be zero

• C

  ‘B’ and ‘E’ both may not be zero and $\overrightarrow{\mathrm{B}} \mathrm{and} \overrightarrow{\mathrm{E}}$ must be patallel.

• D

  ‘B’ must be zero but ‘E’ may not be zero.
