Question

An electron moves in a circle of radius 10 cm with a ons constant speed of 4 0 x 10 ms find the electric current at a point the ver on the circle

Answer 1

Answer:

As

Q = It

and t = s/v

and here s(distance)=2πr

and velocity is 40 x 10m/s =400m/s

So t =2π10/400x100

t=π/2000

=1.57x10^-3 s

I =q/t

I = 1.6*10^-19 /1.57*10^-3

I= Approximately 1* 10^-16 C
