Calculate the de broglie wavelength of an electron accelerated from rest through a potential difference of (a) 100 v, (b) 1.0 kv, (c) 100 kv.

(a)

(b)

(c)

Explanation:

Given that,

(a) An electron accelerated from rest through a potential difference of 100 V. The De Broglie wavelength in terms of potential difference is given by :

Where

m and e are the mass of and charge on an electron

On solving,

V = 100 V

(b) V = 1 kV = 1000 V

(c) If

Hence, this is the required solution.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
