# An electron falls through a distance of $1.5\; cm$ in a uniform electric field of magnitude $2 \times 10^4 N/C$. At the same magnitude, the direction of the field is reversed and a proton is made to fall through the same distance. The ratio of the time of the fall of the electron to the time of the fall of the proton is

The ratio of the time of the fall of the electron to the time of the fall of the proton is $\frac{29}{1300}$
