why reflection coefficient R=1 in step potential though there happens transmission also as a negative exponential when E<V0

There is no transmission when E<V0 for a step potential ... that would mean the particle was traveling inside the classically forbidden region ...
 
The coefficients R and T are determined by the probability of an incident particle traveling to - or + infiity.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
