1.	An unknown particle having double charge as proton itself moves with wavelenght lambda, if it is accelerated from rest through a potential difference of(V)/(8)voltus. While proton itself moves with same wavelenght lambda when acceleratedfrom rest thought a potentialdifference 'V' volts. Theparticls is
Answer» `He^(+)` `Li^(2)ion` `He^(2+)` `Be^(2+)` SOLUTION :`(LAMBDA)=(H)/SQRT(2mxxexxV)` `(lambda)=(h)/sqrt(2xxm'xx2exx(V)/(8))` `mxx2exx(V)/(8)=mxxexxv` `m'=4m`
