The ratio of the de Broglie wavelength of a proton and alpha particles

1.	The ratio of the de Broglie wavelength of a proton and alpha particles will be `1:2` if theirA. velocity are in the ratio `1:8`B. velocity are in the ratio `8:1`C. kinetic energy are in the ratio `1:64`D. kinetic energy are in the ratio `1:256`
Answer» Correct Answer - B `lambda=v` then `lambda=h/(mV)` or `lambda^(2)=h/m` So, `lambda=sqrt(h/m)`
