proton is 1.67 x 10-27 kg and h is 6.63 x 10-34 Js
1) 0.032 nm
2) 2.5 nm
3) 14.0 nm
4) 0.4 nm

Answer 1

The answer would be 14.0 nm

Answer 2

Answer:

option 4

Explanation:

λ=$\frac{h}{mv\\\\}$

this is debroglie,s eqn

by putting the values for h,m and v weget 3.9 x 10(power-10) i,e, 0.39 nm or approximately 0.4 nm
