Additional Materials: Multiple Choice Answer Sheet Soft clean eraser Soft pencil (type B or HB is recommended)
READ THESE INSTRUCTIONS FIRST Write in soft pencil. Do not use staples, paper clips, glue or correction fluid. Write your name, Centre number and candidate number on the Answer Sheet in the spaces provided unless this has been done for you. DO NOT WRITE IN ANY BARCODES. There are forty 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 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 working should be done in this booklet. Electronic calculators may be used.

12 A box is shown resting on the ground. Newton’s third law implies that four forces of equal magnitude are involved. These forces are labelled P, Q, R and S.
Forces P and Q act on the box. Forces R and S act on the Earth.
For clarity, the forces are shown slightly separated.

Which statement about the forces is correct?
A P is the equal and opposite force to Q and both are forces of contact.
B Q is the equal and opposite force to P and both are gravitational forces.
C R is the equal and opposite force to S and both are forces of contact.
D S is the equal and opposite force to Q and both are gravitational forces. 13 Two spheres travel along the same line with velocities u1 and u2. They collide and after collision
