Transcribed Image Text:A negative charge is moving faster along the x-axis. Specify the direction of the electric field. +x along-x axis No enough information along + x axis Opposite to the direction of acceleration
Expert Solution
Step 1

Here we are given a charge which is travelling with acceleration.

Charged particle moves under the application of an external field. +ve charge tends to feel force in the field direction and hence move along the similar direction. But a -ve charge experiences a force against the field direction and hence tend to move along the reverse direction. 

 

Step 2
  • As per the given figure, a -ve charge is moving along the +x axis with acceleration; therefore, applied electric field would be in -ve x-direction.
  • Since the particle is a -ve charge that means it is proceeding in the opposite path of the external electric field.

Therefore, option (a) and (d) are correct options.
