Sample NECO SSCE Physics 2018 questions

1. A micrometer screw gauge has a pitch of 0.5 mm and 50 divisions on its circular scale. What is its least count?
  1. 0.01 mm
  2. 0.1 mm
  3. 0.25 mm
  4. 25 mm

Answer: A. 0.01 mm

The least count is the pitch divided by the number of circular-scale divisions, giving 0.5/50 = 0.01 mm.

2. How many significant figures are present in 0.004560?
  1. 3
  2. 4
  3. 5
  4. 6

Answer: B. 4

Leading zeros are not significant, while the trailing zero after the decimal is significant, so there are four significant figures.

3. Which of the following quantities is a vector?
  1. Mass
  2. Temperature
  3. Displacement
  4. Time

Answer: C. Displacement

Displacement has both magnitude and direction, whereas the other listed quantities are scalars.

4. Two forces of 6 N and 8 N act at right angles to each other. What is the magnitude of their resultant?
  1. 2 N
  2. 7 N
  3. 14 N
  4. 10 N

Answer: D. 10 N

For perpendicular forces, the resultant is sqrt(6^2 + 8^2) = 10 N.

5. A cyclist travels 120 m in 15 s at uniform speed. What is the cyclist's speed?
  1. 8 m/s
  2. 15 m/s
  3. 105 m/s
  4. 1800 m/s

Answer: A. 8 m/s

Speed is distance divided by time, so 120/15 = 8 m/s.
