Circumference = 2πr
Circumference covered by the first electron = 2πr
Circumference covered by the second electron = 2π(4r)
= 8πr
Assuming the electrons move with the same speed = s
Time taken by first electron = 2πr/s
Time taken by the second electron = 8πr/s
The ratio of the times taken by them to complete one revolution
= 2πr/s : 8πr/s
= 2 : 8
= 1 : 4

Answer:
Explanation:
Circumference covered by the first electron = 2πr
Circumference covered by the second electron = 2π(4r)
= 8πr
Assuming the electrons move with the same speed = s
Time taken by first electron = 2πr/s
Time taken by the second electron = 8πr/s
The ratio of the times taken by them to complete one revolution
= 2πr/s : 8πr/s
= 2 : 8
= 1 : 4
