A 100 mV signal at 50 Hz is measured on an oscilloscope due to the effect of a nearby mains electricity cable coupling an unwanted signal to the oscilloscope input. The mains voltage is 230 Virma, and the oscilloscope has an input resistance of 1 MO. Estimate the coupling capacitance between the oscilloscope input and the adjacent mains electricity supply.
