- Homework Statement
- Two fixed identical metallic spheres A and B of radius R=50cm each are placed on a non-conducting plane at a very large distance from each other and they are connected by a coil of inductance L=9mH as shown in figure. One of the spheres (say A) is imparted an initial charge and the other is kept uncharged. The switch S is closed at t=0. After what minimum time t does the charge on the first sphere decrease to half of its initial value ?
- Relevant Equations
- Loop law: kq/r- L di/dt -kq/r=0
where L is inductance, q is initial charge on spheres.
I tried applying loop law but I am not really sure we don't really have a closed loop here.
I guess they're testing some concept here that I'm not very good at (Why do i keep coming back to mutual inductance for some reason:|)
Any help will be appreciated:)
