1. An electron is initially at rest before accelerating uniformly from a negatively charged plate to a positively charged plate separated by a distance d. The voltage applied across the plates is equal to V. 

Which statements are correct?

1. The time it takes for an electron to travel a distance d depends on the square root of its mass-to-charge ratio 

2. Doubling the voltage causes the time it takes for the electron to travel a distance d to halve

3. The number of electrons incident on the positively charged plate each second is inversely proportional to the distance d
