(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.
The angular momentum of the person is given by:
where
is the mass of the person, 
is the tangential velocity, and 
is the distance of the person from the center of rotation. Using these data, we find
where
