- A negative charge of -0.0005 C exerts an attractive force of 9.0 N on a second charge that is 10 m. away. What is the magnitude of the second charge?arrow_forwardWhat do you understand by 'instrinsic strength' of a solid dielectric? How does breakdown occur due to electrons in a solid dielectric?arrow_forwardFour point charges are placed at corners of a square . At the top left is a charge of - 1 C, at the top right is a charge of - 2 C, at the bottom right is a charge of -3 Cand at the bottom left is a charge of - 4 C.

- Electric field terminates at. Both positive and negative Positive charge Negative charge Neither positive nor negativearrow_forwardDry air will begin to ionise when the electric field strength reaches about 3 MV/m (i.e. 3 x 106 V/m), resulting in electrical breakdown. This can result in a spark or arc discharge between conductors separated by air. Assume that you have two parallel conducting plates separated by air, with a large distance d between them, and you apply a voltage of V=10000 Volts to the plates, as seen in the Figure A4, and you gradually decrease the distance between the plates, while keeping the voltage constant. How close can you bring these two plates together, before an electrical spark flies from one plate to the other? For the value of the distance d between the plates you found above, calculate the capacitance of the resulting parallel plate capacitor, and the total charge q stored in the capacitor, if the area of the plates is 1m?.
