A charged particle with a velocity 
passes undeflected through electric field and magnetic fields in mutually perpendicular directions. The magnetic field is 15 T. The magnitude of electric field will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
The charged particle goes undeflected through both the fields, therefore force experience by charged particle due magnetic field must be equal to the force experienced by the charge particle due to electric field, i.e.
