Expert Solution

Step 1

Since you have posted a question with multiple sub-parts, and as per the guidelines we can only solve three sub-parts for you at a time. To get the remaining sub-part to be solved please re-post the complete question and mention the sub-parts to be solved.

Given data-

Charge of a free electron,

$q_{1} = - e = - 1.6 \times 10^{- 19} C$

Charge of the nucleus,

$q_{2} = + 6 e = + 6 (1.60 \times 10^{- 19}) C$

Mass of the electron is given by

$m_{e} = 9.11 \times 10^{- 31} k g$

Speed of the electron at point $P_{1}$ is

$v_{1} = 3.00 \times 10^{6} m / s$
