An alpha -particle and a proton are accelerated from rest through the same potential difference V. Find the ratio of de Broglie wavelengths associated with them.

A electron beam particle is accelerated from rest through a potential difference of V volt. The speed of the particle is

The answer to each of the following questions is a single-digit integer ranging from 0 to 9. Darken the correct digit. There is one particle A having charge q and mass m. There is another particle B of charge eight times and mass two times to that of A. Both the particles are accelerated through the same potential difference. Let speeds acquired by the particles A and B be v_(A) and v_(B) respectively, then calculate v_(B)//v_(A) .
