use the formula ∆x × ∆m∆V=nh/4π

its okay
sorry i not able to change ans
so use usr lamda =h/mv
calculate h
then put the value of h into ∆x ×∆v=h/4π
but i think lamda=h/mv is used only in the case of electron , because m= mass of electron. is it ?
no this hypothesis of your is wrong
no this hypothesis of your is wrong
ohh
so should i use it in this case too ?
