Explanation:
(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
Here, eV = 50 eV
The frequency of electron is given by :
(b) The mass of the proton,
The De Broglie wavelength is given by :
The frequency of proton is given by :
Hence, this is the required solution.

<u>Force</u><u> </u><u>is</u><u> </u><u>2</u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>^</u><u>-</u><u>4</u><u> </u><u>N</u>
Explanation:
F is force
I is current
r is separation distance
gamma is a constant
l is wire length
Answer:
In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator.
