Question

an electron travelling with a speed of 8×100m/s passes through a sheet of aluminum of 1mm thick and emerges with a speed of 2×100000.calculate roughly (i)the accerlation through the sheet assuming it to be constant an(ii)the time taken to pass through the sheet.​

Answer 1

Answer:

The distance covered by the electron in this time will be

Explanation:

Given that,

Speed

Acceleration

Let us consider initial velocity = u

Final velocity = 2 u

Using equation of motion

The distance is the product of the speed and time.

The distance covered by the electron in this time will be

Hence, The distance covered by the electron in this time will be
