QUESTION 1: MULTIPLE-CHOICE QUESTIONS
Various options are provided as possible answers to the following questions. Choose
the answer and write only the letter (A–D) next to the question numbers (1.1 to 1.10) in
the ANSWER BOOK, e.g. 1.11 D.
1.1 Two forces, F 1 and F 2 , act on a point. If F 1 and F 2 act in the same direction
the maximum resultant has a magnitude of 13 N. If forces F 1 and F 2 act in
opposite directions the magnitude of the minimum resultant is 3 N. The
magnitude of the two forces, in newton, is …
A 8 and 5.
B 16 and 10.
C 3 and 10.
D 10 and 7. (2)
1.2 A free-moving block slides down an inclined plane at a CONSTANT
VELOCITY. This means that the …
A frictional force acting on the block is zero.
B net force acting on the block is in the direction down the slope of the
plane.
C net force acting on the block is zero.
D component of weight parallel to the plane is greater than the frictional
force. (2)

angle of 45º to the horizontal. The trolley experiences a constant frictional
force of 60 N.
