Write your name, register number and class in the spaces at the top of this page. Do not use staples, paper clips, highlighters, glue or correction fluid on the Multiple Choice Optical Answer Sheet (OAS) provided. Write in soft pencil your name, class and register number on the Optical Answer Sheet. There are thirty questions in this paper. Answer all questions. For each question there are four possible answers, A, B, C and D. Choose the one you consider correct and record your choice in soft pencil on the Optical Answer Sheet. INFORMATION FOR CANDIDATES Each correct answer will score one mark. A mark will not be deducted for a wrong answer. The use of an approved scientific calculator is expected, where appropriate. Any rough working should be done in this booklet. The acceleration due to gravity (or gravitational field strength) g is taken to be 10 m s -2 (or 10 N kg-1) near the Earth’s surface.
