Problem 91 from 200 Puzzling Physics Problems

So hello everyone in this video I am going to solve problem 91 from 200 Puzzling Physics problems which is based on electrostatics I hope that you are going to enjoy it. The question says: A plastic ball, of diameter 1 cm and carrying a uniform charge of 10-8 C, is suspended by an insulating string with its lowest point 1 cm above a large container of brine (salted water). As a result, the surface of the water below the ball wells up a little. How large is the rise in water level immediately below the ball? Ignore the effect of surface tension, and take the density of salted water to be 1000 kg m-3. Watch the entire video so that you can understand the compete video.
