Answered by terex

use the formula ∆x × ∆m∆V=nh/4π

guitarboy251pc4hgr: its okay

terex: sorry i not able to change ans

terex: so use usr lamda =h/mv

terex: calculate h

terex: then put the value of h into ∆x ×∆v=h/4π

guitarboy251pc4hgr: but i think lamda=h/mv is used only in the case of electron , because m= mass of electron. is it ?

terex: no this hypothesis of your is wrong

guitarboy251pc4hgr: ohh

guitarboy251pc4hgr: so should i use it in this case too ?
