1.	A body of mass x kg is moving with avelocity of 100 ms^(-1) , its de-Broglie wavelength is 6.62xx10^(-35) m . Hence x is (h=6.62xx10^(-34) Js)
Answer» 0.25 kg 0.15 kg 0.2 kg 0.1 kg Solution :According to de-Broglie's EQUATION , `lambda =H/"mv" RARR 6.62xx10^(-35) =(6.62xx10^(-34)) /(x XX 100) rArr x =0.1 kg `
