Expert Answer
let the electric field between the two parallel conductors is E.
Then the force on proton = q E, where q is the charge of the proton
So the acceleration in the motion of proton, ap = q E / mp
let the proton meets the electron at x distance away from the positively charged plate in time t. then using the second equation of motion
x = 0 + (1/2) ap t2 = (1/2) (q E / mp )t2 ...............(1)
The force on the electron = - q E, q is the charge of electron
So the acceleration of the motion of electron, ae = q E / m
Again using the second equation of motion,
5 - x = 0 + (1/2) ae t2 = (1/2) (q E / me )t2 ...............(2)
On dividing eq. (2) by eq. (1)
(5 - x) / x = (mp / me) = 1835
5/x = 1 + 1835
x = 5 / 1836 = 0.0028 cm
