Question

An electron in a research apparatus follows a circular path. On the electron's first circuit of the apparatus, its speed is vo and the radius of circular path is R. Each time it makes one circuit, it passes a short region where it receives a "kick" and gains an additional speed of Vo 100 The electron follows a circular path such that the magnitude of its acceleration is always the same. What is the radius of the circular path after the electron has received 10 kicks?

Answer 1

Answer:

I=q/t

given values,

⇒ Radius =10cm=0.1m

     Velocity =5×106m/s

⇒

$t = \frac{2\pi \: r}{v}$

     

$\frac{2 \times 3.14 \times 0.1}{5 \times 10 {}^{6} }$

          =0.125×10−6

⇒

$i \: = \geqslant \frac{q}{t}$

         =

$\frac{1.6 \times 10 {}^{ - 19} }{0.1256 \times 10 {}^{ - 6} }$

         =12.738×10−13

         =1.273×10−12A

 Hence, the answer is 1.273×10−¹²A.
