A particle of charge - q and mass m moves in a circular orbit about a fixed charge + Q. Show that the "r 3 α T 2 " law, is satisfied, where r is the radius of orbit and T is time period.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
centripetal force F = 
∴ 
= 
⇒ 
= v 2
& T = 
∴ T 2 = 
= 
∴ T 2 α r 3 . Hence proved
