Explanation / Answer

Here,

let the acceleration of the electron is a1

Using second law of motion

a1 = e * E/me

a1 = 1.602 *10^-19 * 7.49/9.11 *10^-31

a1 = 1.32 *10^12 m/s^2

for the proton

acceleration is a2

Using second law of motion

a2 = 1.602 *10^-19 * 7.49/1.67 *10^-27

a2 = 7.17 *10^8 m/s^2

Now , let the time taken by them to pass is t

0.5 * a1 * t^2 + 0.5 * a2 * t^2 = 0.0446

0.5 * 1.32 *10^12 * t^2 + 0.5 * 7.17 *10^8 * t^2 = 0.0446

solving for t

t = 2.6 * 10^-7 s

Now , distance of passing from positive plate = distance travelled by proton in this time

distance of passing from positive plate = 0.5 * 7.17 *10^8 * (2.6 * 10^-7)^2

distance of passing from positive plate = 2.423 *10^-5 m

the distance of passing from positive plate is 2.423 *10^-5 m
