Explanation:
It is given that,
Voltage,
De broglie wavelength in terms of voltage is given by :
m and e are the mass and charge on electron. So,
So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.

Answer:
34.70 N
Explanation:
Given :
F~ 1 = 43 N in direction 38◦
F~ 2 = 26 N in direction −140◦
F~ 3 = 27 N in direction 110◦
Therefore,
F~x = 43 cos (38) + 26 cos (-140) + 27 cos (110)
= 43 (0.7) + 26 (-0.7) + 27 (-0.3)
= 3.8
F~y = 43 sin (38) + 26 sin (-140) + 27 sin (110)
= 43 (0.6) + 26 (-0.6) + 27 (0.9)
= 34.5
so, F~ =
= 34.70 N
