Solution
Given: an electron revolving in the path of a circle of radius of 0.5×10−10m at a frequency of 5×1015 cycles/sec
To find the electric current in the circle
Solution:
The formulas used
current=chargetime
and Time period=1frequency
and distance=2πr
According to the question, r=0.5×10−10m, frequency = 5×1015 cycles/sec
