Answer» For electrons wavelength = 12.27/√V A° so, W1 = 12.27/√50 W2 = 12.27/√200 = 12.27/2√50 = W1/2 so, W2/w1 = 1/2 => W1/w2 = 2:1 ... ( for 50v :200v) option 4

Answer»

For electrons wavelength = 12.27/√V A°

so, W1 = 12.27/√50

W2 = 12.27/√200 = 12.27/2√50 = W1/2

so, W2/w1 = 1/2

=> W1/w2 = 2:1 ... ( for 50v :200v)

option 4
