been struggling with this question: please show steps

A beam of charged particles moves undeflected through a region of perpendicular electric and magnetic fields. The magnetic field has a magnitude of 2.0  10–3 T. The electric field is produced by two parallel plates 3.0 cm apart with a potential difference of 3.0  102 V. The speed of the particles is:
 

 

 
4.5  103 m/s
 
7.0  104 m/s
 
2.5  105 m/s
 
5.0  106 m/s
Expert Solution
Step 1: INTRODUCTION

Given Data:

The magnitude of the magnetic field is B equals 2 cross times 10 to the power of negative 3 end exponent space T

The distance between the plates is d equals 3 space c m equals 0.03 space m

The potential difference is V equals 3 cross times 10 squared space V

The electric field is defined as 

E equals V over d.... left parenthesis 1 right parenthesis

For undeflected condition,

F subscript E equals F subscript B
q E equals B q v
space space v space equals E over B.... left parenthesis 2 right parenthesis

v is the velocity of the particle.
