A photodiode is in series with a 10 kΩ resistor. A laser beam with wavelength 532 nanometer shines on this photodiode such that the entire beam is incident on its active area. The photodiode responsivity is 0.5 ampere per watt (A/W) at this wavelength. If a voltage of 10 millivolts (mV) is developed across the 10 kΩ resistor, the laser power incident on the photodiode is ________ microwatts (µW). (Round off to one decimal place). Assume that the dark current of the photodiode is zero.
