Homework Statement

a small sphere carries a charge of 8.34nC in whirled in a circle at the end of an insulating string. The angular speed is 116 Pi rad/s. what's the average current does this rotating charge represent

Homework Equations

I= q/t
w= theta/t

The Attempt at a Solution

116 pi rad/sec * 1 rev/min

What is current?

What units are you asked to represent it in?

It might be useful to figure how many times the charge will pass a particular point a sec.

They give you that it revolves at 116π radians/sec so how many times a sec ?

Current is I (amps) where its charge(Q) / (t) times in secs. so 116/60?, is it 8.34x1e-9/ (116 pi/60)?

Current is I (amps) where its charge(Q) / (t) times in secs. so 116/60?, is it 8.34x1e-9/ (116 pi/60)?

1. How many radians in a revolution?

2. What's with the 60, when they give you ω in radians/sec already?

 

[xswtxoj]

116 pi rad/ sec * 60secs/1 min* 1rev/2pi rad

 

[LowlyPion]

116 pi rad/ sec * 60secs/1 min* 1rev/2pi rad

Why do you want it in radians/minute when current is in amps which are Coulombs/s?
