Question

In an atom electrons revolves around the nucleus along a path of radius 0.72 $9.4 \times 10 ^ { 18 }$ revolution per second. The equivalent current is

• A. 1.2 A
• B. 1.5 A
• C. 1.4 A
• D. 1.8 A

Answer 1

Answer: (B)

1.5 A

Answer 2

:Radius of electron orbit

Frequency of revolution of electron in orbit of given atom)

$v = 9.4 \times 10 ^ { 18 }$rev/s

(where T is time period of revolution of electron in orbit

$\therefore$Then equivalent current is,
