Question:medium

If the total energy of an electron in an orbit is positive, then

Show Hint

The sign of the total energy determines the type of orbit in a central force system (like gravity or electrostatics): - \(E<0\): Bound, closed orbit (ellipse or circle). - \(E = 0\): Marginally unbound, parabolic trajectory. - \(E>0\): Unbound, hyperbolic trajectory.

electron will revolve in a circular orbit
electron will revolve in an elliptical orbit
electron will not follow a closed orbit
electron will fall into the nucleus
