Do not use staples, paper clips, glue or correction tape/fluid. Write your name, register number and class on the Question Paper and on the Answer Sheet in the spaces provided. There are thirty questions on 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 in the spaces provided on the separate Answer Sheet. Read the instructions on the Answer Sheet very carefully. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. Any rough working should be done in this booklet. The use of an approved scientific calculator is expected, where appropriate. Take the acceleration due to gravi ty g (or gravitational field strength) to be 10 m s -2 (or 10 N kg -1) near the Earth’s surface. This document consists of 11 printed pages and 1 blank page.
