Suppose you are building a king-arthur-themed amusement park. you haveconstructed a stone with a hole in it, and a sword that fits in the hole. you have built acircuit into the sword and stone so that, when the circuit is switched on, the tip of the swordhas a chargeqon it, and the bottom of the hole has a charge−qon it. (don’t worry abouthow one would build such a circuit - we’ll get there later in the course.) with the swordin the hole, the two charges are separated by a distanced= 5cm. estimate how large thechargeqmust be so that even the strongest amusement park visitor will not be able to drawthe sword from the stone (while the circuit is switched on.)important: some estimation is required – you will need to justify your estimate.
