Homework Statement


A particle having charge 8 nC moves in circular orbit with angular speed of 100 π rad/s. Find the average current produced!
a. 0.2 μA
b. 0.3 μA
c. 0.4 μA
d. 0.5 μA
e. 0.6 μA

Homework Equations


Q = I.t

The Attempt at a Solution


The equation I can think of is Q = I.t. I don't know how to find t and I also don't know what the use of angular speed in this question.

Thanks

I get it. I find the period then it's the time. The answer is C

Thanks a lot
