In a double slit experiment,a beam of electrons strikes a pair of slits.The slits are 15 μm apart,and the first interference maximum lies at an angle of 0.50 µrad from the center of the interference pattern.What is the momentum of the incoming electrons? (h = 6.626 × 10-34 J ∙ s,mel = 9.11 × 10-31 kg)
A) 4.4 × 10-23 kg ∙ m/s
B) 2.2 × 10-23 kg ∙ m/s
C) 1.1 × 10-23 kg ∙ m/s
D) 6.6 × 10-23 kg ∙ m/s
E) 8.8 × 10-23 kg ∙ m/s
