Answer:
The angular acceleration is
Explanation:
From the question we are told that
The moment of inertia is
The net torque is
Generally the net torque is mathematically represented as
Where is the angular acceleration so
substituting values
Answer:
Given that
speed u=4*10^6 m/s
electric field E=4*10^3 N/c
distance b/w the plates d=2 cm
basing on the concept of the electrostatices
now we find the acceleration b/w the plates to find the horizontal distance traveled by the electron when it hits the plate.
acceleration a=qE/m==
m/s
now we find the horizontal distance traveled by electrons hit the plates
horizontal distance
=
== 3 cm
