The wind is blowing in the direction of a vector pointing at an angle 30 degrees to the east of due north, at 35 miles/hour. An
airplane that can go 320 miles/hour in still air points itself due north at the start of a race. The other airplane points itself with the wind directly at its back. It can go 305 miles/hour. How long will it take each plane to cover 1 degree of latitude?

The De Broglie wavelength of the electron is
And we can use De Broglie's relationship to find its momentum:
Given
, with m being the electron mass and v its velocity, we can find the electron's velocity:
This velocity is quite small compared to the speed of light, so the electron is non-relativistic and we can find its kinetic energy by using the non-relativistic formula:

Answer:
Explanation:
Deflection in the drop is due to electric field force
so we will have
acceleration of the drop is given as
now we know that time to cross the plates is given as
now the deflection is given as
