A proton orbits just at the surface of a charged sphere of radius 0.83 cm. If the speed of the proton is 4.96 X105 m/s, what is the charge on the sphere?
proton mass = 1.67e-27
proton charge = 1.6e-19
Radius = .0083 meters
I thought maybe F = (mv²)/r
((1.67e-27)(4.96e5)²)/.0083
Then E=F/q
But this doesn't seem to be right.
Any help would be appreciated. I have tried it a couple times with no luck. Just need to get in the right direction. Thank you in advance!
