6 7 A light dependent resistor (LDR) and a resistor are connected to a battery, as shown. The intensity of light incident on the LDR increases. Which row of the table describes the change in the resistance of the LDR and the change in the potential difference across the resistor? Resistance of LDR Potential difference across the resistor A decreases decreases B decreases increases C increases decreases D increases increases (Total for Question 7 = 1 mark) 8 A potential difference is applied across two parallel plates. A particle carrying a charge of +0.1 C is placed between the plates and experiences a force F. The distance between the plates is halved. The potential difference remains constant. Which of the following is now equal to the electric field strength between the plates? A   5F B 10F C 20F D 40F (Total for Question 8 = 1 mark)
