In a scanning tunneling microscope the tunneling current is found to decrease by a factor of 0.00013 when the distance between the tip and the surface is moved from w to 3w. Find the probability, p, for an electron to tunnel at the original tip distance (w). (Give your answer in exponential notation to two decimal places, e.g. 7.34e-6) Add your answer
