apply lambda=hc/E...where E=180eV
Chetan Mandayam Nayakar
p2/2m=E, p=sqrt(2mE),λ=h/(2π)
Vikas TU
For de-broglie wavelength
lamda = underoot 150/V
where V is the Voltage
Lamda = underroot150/180
= underroot5/6 is the ansr.
Abhishekh kumar sharma
we have e=hv ... 1
and v=c\λ
substitue v in 1 to get e=hc\λ
then lambda =hc\e

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
