An electron moves straight inside a charged parallel plate capacitor of uniform surface charge density 
. The space between the plates is filled with constant magnetic field of induction 
. Neglect gravity, the time of straight line motion of the electron in the capacitor is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The net electric field ⇒ 
The net force acting on the electron is zero because it moves with constant velocity.
The time of motion inside the capacitor
