Approximation of the probability by the Quantum tunneling. ?
Keeping the constant speed of 0.6m/s, a marble of mass 18 g rolls back and forth across a shoebox that is 14cm high and 2mm thick. Approximate the probability of its escaping through the wall of the box by quantum tunneling. (prepare the answer in the form 10n, where n is an exponent with 1 significant figure, eg -5e15.)
What is the value of n?
