An electron moves in a circle of radius 10cm

Asked by admin @ 20/08/2021 in Physics viewed by 306 People

an electron moves in a circle of radius 10 centimetre with a constant speed 5.0*10^6 m/s. Find the current at a point on circle.

Answered by admin @ 20/08/2021

I= $\frac{q}{T}$

given values,
q=1.6×10⁻¹⁹ C
radius=10cm=0.1 m
velocity=5×10⁶ m/s

T=2πr/v
= $\frac{2*3.14*0.1}{5*10^6}$
=0.1256×10⁻⁶

I= $\frac{q}{T}$
=1.6×10⁻¹⁹/0.1256×10⁻⁶
=12.738×10⁻¹³
=1.273×10⁻¹² A
