An electron of mass M initially at rest, moves through a certain distance in a uniform electric field in timet,
A proton of mass M also initially at rest, takes time t, to move through an equal distance in this riform
electric field. Neglecting the effect of gravity, the ratio t/t, is nearly equal to

Answer:
Explanation:
If the acceleration is a then the distance s travelled in time t is given by
Therefore for electron
And for Electron
Thus,
.......... (1)
Force on electron in an electric field E
Thus the acceleration of the electron if its mass is
Similarly the acceleration of the proton
Therefore,
Therefore, from (1)

Answer:
√ ae/ ap = √ mp/me
Explanation:
Mass of the electron = M (Given)
Mass of the proton = M (Given)
Time = t (Given)
Electrostatic force, FE = eE (for both electron and proton)
But acceleration of electron, ae =FE/me whereas -
acceleration of proton, ap = FE/mp
S = 1/2at²1 = 1/2apt²2
Therefore,
t2/t1 = √ ae/ ap
t2/ t1 = √ ae/ ap = √ mp/me
Thus, the ratio is nearly equal to - √ ae/ ap = √ mp/me
