A proton and aLi3+nucleus are accelerated by the same potential. IfλLiandλpdenote the de Broglie wavelengths ofLi3+and proton respectively, then the value ofλLiλpisx×10-1. The value ofxis _____ (Rounded off to the nearest integer) [Mass ofLi3+=8.3mass of proton]

Answer:
2.00
Solution:

λ=h2mqV

λLiλp=mpeVmLi3eV  mLi=8.3 mp

λLiλp=18.3×3=15=0.2=2×10-1
