Lets calculate the capacitance of cloud,
C = eo A/d =8.85*10-12*pi*1100*1100/1600 = 2.1*10-8 F
now charge, Q=CV
Q=1020*1.6*10-19 Because charge of 1 electron is1.6*10-19
so potential difference, V=Q/C = 1020*1.6*10-19/[2.1*10-8 ] = 7.77* 10-9 V
In a thunderstorm, lightning can transfer more than 1020 electrons in a single strike. Approximating a...
A lightning strike can transfer as much as 1020 electrons from the cloud to the ground. If the strike lasts 2ms, what is the average electric current in the lightning
8. 0/12.5 points | Previous Answers ZinPhysLS3 17.P020 We model the surface of Earth and a cloud layer at 975 m height as a parallel plate capacitor. (a) If the clouds cover an area of 1.6 km, what is the capacitance of our model (in nF)? (b) If an electric field strength exceeding 3.0 x 106 N/C causes lightning (the air becomes conducting), what is the maximum charge (in C) that can be present on the cloud layer? 40.95 (c)...
Tutorial 9: Electricity I (week 10) 1) A typical thunderstorm can be regarded as comprising two charges of +40 C and -40 C, separated in air by a distance of 5 km Calculate the magnitude of the force between the charges 2) Four charges are arranged at the corners of a square with sides length, L, as shown Q: 4 mC, q = 2 mC and L = 10 cm a) Find the magnitude of the .Q net force on...
